Michael Carrick - Head Coach for the remainder of the season

I feel like I'm losing my mind trying to read this in-depth analysis of his coaching ability based on his time at Boro. IMO there literally isn't a more irrelevant thing to talk about than this.

Because first off, he will have access to better coaches at United who can work on the technical aspects with the team. He doesn't have to be a coaching genius. Secondly, Boro weakened in the transfer market during his reign something that 100% is not happening here. The team will have access to funds, we are constantly among the top 4 spenders. Now it seems, with the structure put in place by INEOS, we might also have better scouting and target selection in the transfer market too. If this year is anything to go by, anyway.

Thirdly, I believe in many cases with managers that their success or failure at a club is completely circumstantial, because the success equation is multi-factorial. Managers are only one part, then there's the coaches, the players, the scouting department, the board and even good ol' lady luck. My point is that previous success is rarely a good predictor for future success. A good manager can fail at a club and a bad manager can succeed and made to look good, due to other circumstances. My point is, the past is rarely a good predictor for the future and it's certainly far less accurate than the present.

Fourthly and very importantly, I am adamant that there are two ways to manage a team: One is being a very strong tactical coach like Pep or Klopp, someone who can implements their very strong vision about how the team should play football. The other one is just being a sensible decision maker, a good motivator, an intelligent people manager and someone with a bit of charisma or IT factor. That guy tends to also leave some of the tactical coaching to more drilled instructors.

Ferguson in previous decades and Ancelotti and Zidane in the recent era stand out for me as managers without exceptional tactical or coaching skills, but who succeeded in a very demanding job because they fit the latter description. Xabi Alonso on the other hand, who is considered a very strong tactical coach that drilled Leverkusen to perfection, struggled to handle the personalities at Real Madrid and was forced out in less than a year.

We also tried two such coaches recently, with reputation for drilling their own system, in ETH and Amorim and it failed spectacularly. In my opinion this approach of looking for mercurial tactical coaches and then signing targets that align with their specific tactical vision, is like betting it all on your favourite number at the roulette table. It will still end in tears 98% of the time. So, if Carrick makes it to the end of the season with no collapse and he manages to grab 3rd spot against all expectations... then for me the job is his. I don't want to start again with a brand new gamble, while things are looking good for us as is. I'd much rather we keep him and focus the energy on just strengthening the squad for next year. And I don't give single F about his time at Boro, it literally doesn't matter at all.
I completely agree, and as if to provide an example for your point about the importance of context and circumstance, look at Marcelo Gallardo at River. Absolutely worshipped for his first stint at the club, including beating Boca in the final of the Libertadores, for which they put up a statue of him.

He left and went to Saudi, came back a couple of seasons later for his second stint and has just fired/mutually consented because they’ve been rubbish.
 
Imagine that this thread is serious and we are willing to give him a 3 year contract, another disaster for another three years. He's a great interim who profited from the momentum and other teams losing points massively, but let's be realistic.
 
Why not just wait til the end of the season?
To give confidence and certainty to the team that this is the way the club will proceed. I'm not saying that's a good reason to do it, I agree that logically we shouldn't jump the gun, but that's the main argument for it.
 
Everything is relative and narratives form easily. There’s no doubt Ferguson was the tactical mastermind behind the Aberdeen that beat Celtic, Rangers, Bayern and Real Madrid, and the Man United who won the league several times and CL. His assistants up until them were never tactical masterminds, and he often outsmarted tactically acknowledged managers. People tend to simplify the identities of things, and I think the personality on show on the sidelines and in press conferences gave more showing to his authority and engagement - he didn’t like to talk tactics in public for obvious reasons, I think - and if you’re great at onething, you can’t be great at the complementary quality as well, in simple narratives.

The main narrative I think was formed when he got Carlos Quieroz to tactically rejuvenate (particularily defensively, and more than anything for Europe, I believe). That in combination with him becoming more on the sidelines and less on the training pitch, probably gave his players of later era even more of an impression he wasn’t that fussed with tactics. But I think evidence points to him being very much the main architect even when giving Queiroz and Meulensteen more responsibility for tactical development, seen in how he wentin like a Rembrant to reorchestrate things a few times when their approaches had issues (in attack for Queiroz, defensively with Meulensteen).
Anyone who has had a great teacher in something will know too that they always seem like they're talking about really simple and basic things, but try learning the same thing from a less skilled teacher and it will sound far, far more complicated. Being able to convey complex ideas in a simple way is at the heart of good leadership and you can tell SAF had it in spades just by listening to him speak about football.

The certainty is already there- he has a contract to the end of the season. Reassess it then.

When Ole was made permanent early the wheels came off. Why rush in after 7 games when there's still 12 left to go? It's not like we're going to lose him to Real if we don't sign him up now.
 
He’s the manager until the end of the season.

Let him have those games and reassess once the season is over.

It doesn’t need to be any more complicated than that.

To back up your post, in a book about klopp, he says there were meetings with players where he kept it brief and simple so they could remember and understand.
 
This ignores the fact at the same time we also need results, without results none of the other stuff actually matters which is what did for Ruben in the end, so rather than just broad stroke go we need some progressive football we need that and results and in the absence of the former we are still able to get the latter which is far more important

It doesn't ignore it, it explicitly addresses it at the end of the post. Results suffering a bit is inevitable, so there's a balancing act that we need to get right. Finishing 8th and 15th as we have recently is clearly getting it wrong, but if we want to challenge for titles then we need to move to a more progressive style of football.
 
The next step doesn't happen if we keep changing philosophies every 6 months and don't manage two successive seasons in the Champions League.

If there's no decent manager available this summer, it makes zero chance to take another Amorim style punt especially when it could set us back massively. It's possible to have a short term plan that doesn't contradict our longer term goals.

Nobody has mentioned changing philosophies every 6 months, I'm not sure why you brought it up.

What we do know is that the current style of play has a ceiling, and it's below winning titles. In order to become a team that can challenge, we need to move beyond it. That doesn't mean taking a punt on a manager, it could even be Carrick here next season starting us on that journey if he's the right man, but whoever it is needs to be moving beyond this style of football ASAP if we're to harbour any ambitions of winning titles in the next 5-10 years.

The most important part is player recruitment, if we bring in players that can excel in a more proactive style of football, then we can afford to make the transition longer and more smooth.

I think we need to make sure the plan to change the footballing approach is directed from higher up than the manager. If we don't have to tear everything up after every managerial change we'll fare a lot better at not going back to square one when someone doesn't work out. So if Carrick can move us from C to B but not to A, we can simply change manager and carry on with our plan.
 
Giving managers lots of control can be dangerous. Capello signed players for madrid in 06 and Emerson, reyes, cannavaro didnt turn out too well. Others did though. After that the club went back to higher ups signing players. Mourinho was given control and did very well with signings but fell out with the players. After that the club went back to higher ups signings players. When a manager was in great form like Mourinho in 2010 maybe it can work but it is probably better for a club to have people who are above the manager that are capable of signing players and appointing good managers.
 
Imagine that this thread is serious and we are willing to give him a 3 year contract, another disaster for another three years. He's a great interim who profited from the momentum and other teams losing points massively, but let's be realistic.
The momentum was created by Carrick, not Amorim — so what exactly is your argument?
A manager’s job is to create momentum and build belief within the squad. Carrick has done that. He has made the players believe they are good enough to compete and sustain that momentum. That is leadership.
Constant managerial changes create instability. Every time you replace a manager, you create a vacuum that the next one has to spend months trying to fix. That cycle is exactly what has hurt this club in recent years.
Since the OGS era, too many managers have chosen to point fingers at players and sell them off rather than take responsibility themselves, that made our squad real thin . That approach destroys confidence and unity. Carrick, on the other hand, has rebuilt belief instead of tearing it down.
If we finally have momentum, why disrupt it?
 
Carrick has done fantastically well since he took over. Decision on whether he should be offered the permanent job should be taken in the summer, and should not be solely based on where we finish. Good results should definitely go in his favor, but I hope, our director of football looks at other factors while making the decision.
In the same vein, losing out on top 5 should not also automatically rule him out of the job. People need to remember, Amorim’s united picked up a measly 15 points from a fairly easy run of 11 games in November and December. That’s going to catch up with us at some point of time.
 
To add to this, i remember del bosque saying he was confident about playing man united because they were not the best tactically or something like that. It is crazy how ferguson seems to get that criticism. It is hard to picture the most successful coach ever wasn't good at tactics.
I don't think anyone thinks SAF was bad at tactics, he clearly wasn't, but tactics weren't his best asset, his man-management and motivational skills were his best attributes
 
If he can keep us in the Champions League places as the injuries are starting to pile up, it will be another tick for him. We have no left side now if Shaw is out, and our most reliable ball progresser from the back has been out, but the manager has still worked out ways to win. Just wish he was installed earlier.
 
Arteta is potentially going to win a league title because all his rivals have been shit this season. They are on track to get 7 less points than a few seasons ago and are generally poorer in every metric vs that season but might win the league. They are an effective team however you want to look at it. Not good to watch a lot of the time but generally effective. They win games by dominating their opposition.

We are currently not winning games by dominating out opposition. Arsenals style is relatively sustainable even if its not optimum for winning competitive titles. Ours is just not.

Do they? They win games by playing for corners and then stacking 6 players in the 6-yard box, all around the defending goal keeper. But hey maybe it's just me.
 
To back up your post, in a book about klopp, he says there were meetings with players where he kept it brief and simple so they could remember and understand.
In his biography Fergie said he never spent so much time in the video room as 2013, to get the title back from City. Also said he preferred to delegate the day to day coaching in his later years, as it helped him get a bird’s eye view of the team and spot issues with players in training (sometimes before the players even knew themselves, he claimed).

So it really wasn’t the case that he didn’t understand tactics, he just preferred to focus on squad management because we juggled multiple competitions back then without the gulf in resources a team like peak City enjoyed, who could field 2 similar quality XI, so priming the players and conserving their energy, especially for older players like Giggs, Scholes, or those with chronic issues (Rio’s back) takes precedence over tactical minutiae. Even with all that we still regularly suffered defensive injury crises back then, I think there was a CL game in 06 or sth where we had a cb pairing of Carrick and Fletcher.

I agree with most of this. But if we don't get top 5 at this point, it's a huge red flag for me as we're massive favourites to do it. The bookies have us at 92% chance to get top 5. It would be a huge failure from here not to and that would need a really hard looking at. He's done a fantastic job so far and the reason we're in the race for top 5 in the first place is because of these great results, but if we weren't at least in the race for top 5 we'd probably not be talking about him as permenant manager in the first place. It would need to be a such an extreme set of injuries and/or three other teams going on such an extremely unlikely run of wins for a him to get hired if we finish 6th now that it's almost a dealbreaker in my opinion.
 
‘Performance posters’ (I just coined that. feel free to use it) are neglecting that we are in the ‘business end’ of the season now, where performance matters much less. Results - points, are what matters now

Don’t think anyone has an issue with the results, but the understandable focus on results masks whether he is capable of getting us performing the way we need our next manager to. The risk is that we sign him based on results, and we regress next year because he’s simply not good enough at employing a system that allows us to move to that next level. Our results have so far flattered our performances, on the whole. The sustainability is the question.

Hopefully we have a better idea by season end.
 
Someone said earlier loosing 5 games should not rule him out. I disagree.
This interim period is the perfect opportunity to evaluate Carrick the credibility to full time job. One of the key factors is how the squad deal with setbacks and overcome difficulties. It’s the head coach to drill in belief, spirit, and mentality. We had a few during the seven games and came out greatly. Let’s see if we can continue.

The stats would indicate the opposite, if anything.

It's become another one of those things that has been parroted enough times for people to take it as fact.

Same as the "can't find a tactic to beat a low block" stuff that was hilariously still being spouted after Carrick made quite obvious and bold changes to get us the equaliser against West Ham's low block.

Well I think that’s probably a leap of faith that we need to decide on. I’m sure at the moment with 10 games to go, everyone is just trying to put one foot in front of the other in the chase for results.

It's always said with such confidence as well despite being wholly wrong
 
I'd genuinely like to here Pogue's justification for the belief that results haven't flattered the performances under Carrick. I'm yet to hear anyone make that argument compellingly (which is unsurprising given how good our results have been).
 
The stats would indicate the opposite, if anything.

I mean our results have been pretty much perfect so unless you think our performances have been literally perfect then it’s not a particularly controversial statement to make, surely?
 
That's not really what happened though, there's a few factors at play but the guy in the reddit post I linked kind of summed it up. In the first season they were genuinely very good under Carrick, but that was largely because 1) his system hadn't been worked out yet and 2) Akpom was in Championship-Bruno levels of form and they still had issues with low blocks. He lost Akpom and made Boro a more transitional side (they were barely above 50% possession that season) and they struggled, their xG dropped significantly, their xG against went up and their possession skewed much more towards their own 3rd than it previously had. The next season even more teams started to do it and they entered the dreaded horseshoe phase where they'd see lots of the ball but lower quality chances as they struggled to break teams down. They overcommitted chasing goals and got caught at the back.

You don't need to take my word for it. Look at the actual reporting on Boro from the time. Those supporters weren't playing down Carrick so he wouldn't get the Man Utd job, they were just calling it as they saw it. Better players might have gotten Boro promotion under Carrick, but he was never going to get a group of players playing the same way Kompany did at Burnley, for example.
Are you sure? 22/23 — 84 goals from 73.9 xG. 23/24 — 71 goals from 69.5 xG . How is that a significant drop off? How can a difference of 4 goals go from very good to struggling? While also admitting they lost their best player. The top scorer in the league.
They also lost Cameron Archer, Aaron Ramsey, Ryan Giles, Alex Mowatt, Rodrigo Muniz, and Morgan Rogers. How is that not a major rebuild? I don't agree that his system hadn't been worked out yet in the first season at its well know he transformed Boro from a defensive side into an attacking team, consistently creating high-quality chances. I feel that his system took time to implement in his second season due to turnover reflecting in the poor start where they had no wins in the first 7 games. However after getting the team to jell they really took off finishing respectively in 8th all things considered. Also taking the team to the League cup semi finals and beating Chelsea at home is no small accomplishment. Even though they lost the return match.

Defensively from the 22/23 season they had a xga of 48.3 to 55 for the 23/24 season. Would that be significant considering the changeover in personal? Also while admitting that recruitment was a problem. Not getting the right players for his system. Taking everything into account wouldn't you say that Carrick did a pretty good job with the players at his disposal and changeover? I feel that he did a really good job. JMO. If you don't agree that's fine as looking into all the fine details of Carrick's time at Boro its telling me we have the right man in charge. It also is making me more confidant that he has all the right attributes to be a top manager. So thanks for the insight.
 
If we win tomorrow, I'd announce him as the manager for next season. Start planning for the summer which is something we've not been able to do at this stage of the season for a while.

Because the "underlying metrics" that apparently expose our performances as unsustainable don't actually support that narrative.

We were well worth the wins against City, Spurs, Everton and Palace, and the stats reflect that.

The Fulham game we slightly edged in terms of chances, but even then, we were well on top until the penalty and anyone who watched that match would agree that 3-0 would have been a fair result if Maguire hadn't lunged in.

It's only really the Arsenal and West Ham games where you could argue we were a bit lucky, but the Arsenal game was a fairly even affair, and we were basically the only side trying to create something from open play, and the West Ham game only saw them ahead in chances because Carrick made tactical changes to beat the low-block. as they were basically at one decent chance until stoppage time.

This is the exact logic that resulted in us giving Ole the job in March rather than the common sense approach of waiting till the end of the season, where they'd have a bigger sample size to assess. He then blew top 4 for us from March and couldn't buy a win.

We've had a manager on a permanent contract numerous times recently at this stage of the season so I've no idea what you mean we’ve not been able to plan.

Clubs appoint managers in the summer all the time. The club should know what players are on their list and not be making drastic changes based on the manager anyway. And we should be perfectly capable of appointing the manager quickly once the season is officially over.
 
I bet this has already been said, but I will put it forward anyway: things are going great right now for Carrick. But did things not also go great for Ole Gunnar Solskjaer too, when he was in the caretaker role.

But when he got a full-time Managers contract, things went a bit wrong.

Would it not be a good idea (assuming Man United get top 3 or top 4) to reward Carrick, but with some sort of rolling contract, to be reviewed every 6 months or so? He might actually turn it down as it would be a bit of an insult, but it might stop a repeat of the OGS situation where the players performed at 100%+ for him so he got the job, but once he got the job they reverted back to 70-80% performance.....

City and Arsenal were brilliant results, but we have tended to do better against big teams lately that attack us. The consensus here was that he would be judged moreso on the teams playing a low block, which is fair.

As for those, the ‘underlying metrics’ are enhanced against Spurs and Palace in part at least due to the red cards. Spurs are also absolutely dogshite. Granted you have to win those red cards, just like we did against Chelsea earlier in the season under Amorim, but it still will distort the metrics if that’s what you’re hanging your hat on.

West Ham we needed an injury time winner to beat one of the worst teams in the league. Yes he made changes to achieve that, which is also good, but it still was not a great performance.

I think you’re probably being overly generous re Fulham, given we also still ultimately needed an injury time winner to beat them. Again, result trumped overall performance.

I’m not being negative here btw, he’s done a great job so far. But the results have clearly been better than the overall performances which was the original point I made - in part because our results have been practically perfect.

As I say, we’ll have more to work with by season end. 7 games is not enough time to judge really outside of the results.

You're forgetting the first 13(?) games of the season weren't managed by Carrick. If you look at it on a per game basis for Carrick's tenure the drop off is more significant. Combine that with significant weakness at the back, less possession etc. and it's a clear drop off.

You're free too interpret the reasons/mitigations for that drop off how you like, I've made my case already on the matter (and linked a few sources from the time which highlight the issues) so I don't feel the need to labour them again. They're on page 73~.
 
I think we need to make sure the plan to change the footballing approach is directed from higher up than the manager. If we don't have to tear everything up after every managerial change we'll fare a lot better at not going back to square one when someone doesn't work out. So if Carrick can move us from C to B but not to A, we can simply change manager and carry on with our plan.

I couldn't agree more, that's exactly the approach we should be taking.
 
If we win tomorrow, I'd announce him as the manager for next season. Start planning for the summer which is something we've not been able to do at this stage of the season for a while.

I don't understand why we can't wait until the end of the season. Why rush such an important decision? Planning for next season will be taking place regardless of who the manager is, you would hope.
 
If we were in the cups and Europe, I'd be more inclined to giving him the job if he got us top 4. The fact that we are only playing in the PL makes it hard to judge as we're in pretty unique circumstances. Even Rangnick in that turgid year had a tie vs Atletico.

Playing once a week allows more time than he'd ever get to prepare for matches and to basically play the same team every week.

If we were in Europe and the cups, we'd get to know a lot more about his ability by the end of the season. This is what happened with Ole, after a shit hot start by the end of the season things levelled out a bit.

It's just too much of a risk to appoint him on the PL only in a historically weak year for the top teams. Seems like the kind of decision we'll look back on six months into the season and ask ourselves why we made the same mistake again.
