Michael Carrick - Permanent Head Coach

Under Carrick we take a lead, 1 or 2 goals and then defend which results in less possession. Under Amorim we always chased the games, more possession, more pointless shots which increase the volume of shots and cumulative xg.
Apparently this isn't the case, but I'm also too much of a brainlet (and it's step too far into the stat realm for me) to really look into it enough to understand. But if anyone wants to:
The follow up post includes leading/trailing differential.

Not much info here to go off. Needs to be analyzed more.

I do feel like we trailed more often under Amorim, which should not be discounted too easily. It is definitely a good explanation for the discrepancy between xG and points.

Has anyone thought about the idea that the supposition that results eventually have to match the underlying statistics as measured here is only true in this robotic football environment that we have now, where every chance is meticulously worked out beforehand. In a more "free-spirit" and "creative" play style, they may not even have to converge over time.

In other words - the idea that the results and underlying statistics have to converge is dependent on the play style (and consequently, the manager). So I would like to see some data collating how different managers consistently over- or under-perform their underlying statistics - and what does that say about particular play styles. Not necessarily the sustainability of one play style over another.
 
I mean, this isn't a massive surprise. We haven't been that good under Carrick quite often and have ridden our luck far too often. I would broadly say that Carrick has enjoyed a lot of good luck and Amorim enjoyed a fair chunk of bad. I don't think Amorim was our guy but the idea that Carrick has transformed us in anything but results seems ridiculous to me and a huge part of the reason I'm nowhere near convinced he was the right guy to give the job to permanently.

I would perhaps suggest that his results made it almost impossible for anyone else to be given the job however. If we brought in another manager and results weren't instantly great, the pitchforks would have been out and the questions about why Carrick wasn't given the job would be there from day 2.

It's a results business and you make your own luck. Amorim wasn't a good fit and should have been removed after the Europa League final last season.

Carrick was brought in to steady the ship. No more back five nonsense and poor treatment to players such as Mainoo. Keeping things simple was awarded with a deserved 3rd place.

Next season will take care of itself and Carrick will be judged on results once more.

Amorim was a bellend, in addition to being the worst MU manager ever. Luck has nothing to do with it.

Carrick has managed us with class and calm positivity. He has exceeded expectations and deserves all of our support.

The answer, primarily, is Lammens.
 
He‘s a part of it, but Onana (who was terrible) wasn‘t making mistakes every single game. Lammens definitely solved the gk issue though.

Onana/Bayindir between them weren't that far off a mistake every game. They were killing us in games.

Lammens is easily the biggest factor in thos turnaround.

Where do you think we'd have finished this season if we didn't sign him?
 
We looked excellent in big games under Carrick.

It's the midtable teams where we looked a bit suspect at times

so then the analysis for that would be simples....against the better sides he was more pragmatic in the set up, conceded some possession and played on the counter

against mid table teams where we were expected to have more possession they opened up their attack and struggled to defend against the counter which tends to led to the comment made below

You mean he needs a new midfield and strengthen our full backs and probably needs a new CB.

All things any new manager would need.
if you're going to be set up as mentioned above clearly the CM became the most glaring issue if you're going to attack with two wingers, both fullbacks, the CF and the ACM....thus really only defending with 4 and theCM's get over run

as for CB.....i think that would be a mistake bringing in someone else when you have two young guys like Yoro and Heaven in the squad unless you are getting rid of one senior player in maguire/de ligt/licha
 
It's a results business and you make your own luck.

Thats such a BS statement. You don't make the opposition miss sitters. You don't make your striker score a few worldies that they have no business scoring. Its just a meaningless saying used to avoid having to engage on a matter of underperformance vs outcome.

Next season will take care of itself and Carrick will be judged on results once more.

He will be judged on results and he will be judged on performances. Unless you are Arsenal, most of the big clubs expect good football as well as results. And I don't think that results are going to be as good as this season even after we have spend £200m+ on players. I think the top teams won't be as crap next season and we won't be looking at 3rd place with performances like we have seen this year.

Something like 10 points lower. They were definitely killing us at the start of the season.

We’ve missed enough sitters like most clubs do. As for “have no business” wtf does that even mean. You have no business talking utter bollox.
 
I don’t mind carrot getting the job because there’s so much better going forward, but there’s no way we can sustain playing this way in Europe against some of the better teams because they will just slice us to death. Carrick has to find a happy medium with being offensively attack minded, but a little bit more sound defensively, especially through the middle of the pitch
I thought Jasper was a former Brummie director and comedian
 
I know this Amorim XG chatrer is loosley about Carrick, but let's try to stay on topic.
It would make more sense to just ban all x this and x that completely (and the the other fecking X that used to be something else), personally I don't need any stats to tell be whether a chance is good or not and whether it should be scored or not or whether player A is better than player B at doing Z

This is a bit silly though in this particular context because our opponents have scored some worldies, we’ve missed so many sitters, and we’ve had a bunch of decisions go against us. if someone wanted to do an in depth statistical analysis of our “bad” luck versus “good” luck in our last 17 games I doubt it would reveal very much. Many of our results in tight games have come because we’ve had just that little bit more quality in key moments, which is unsurprising given some of our players.

That’s not to say our performances can’t improve of course - I think most people agree on our issues and where we need to improve.

I'd say easily 10 points.

I think a 4 game swing with those two in goal as opposed to Lammens is very possible.

As someone who has been watching United in action since the mid 80s its far from BS

He'll be mainly judged on results next season you can knock yourself out if you want to think different.
 


I get the feeling that we've accidentally stumbled upon the man to finally solve our midfield issue after all these years
 
I wasn't so warm about MC... But idk I got so pumped. Whatever it will be, good luck Carrick. At least we will know that he will gave his all. He doesn't like slacker or fraud.
 
One of the reasons I was pessimistic about Ole (aside from the periods of very dodgy form) was who he was up against- Klopp and Pep. It just seemed a mismatch and such a disadvantage. Looking at Carrick now, with Pep leaving, he’s not really up against any manager that I look at and think “he’s a genius and I wish he were our manager”. Looking at next season you probably have;

  • Arteta- probably the league champion this year but at a club that historically fails to retain their titles and a mopey fan base.
  • Slot- what a mess he’s in if he stays!
  • Maresca (possible) - elite manager?
  • Alonso- probably the most interesting of the bunch.
  • Emery- very good manager but an underdog.
This is not Klopp, Pep or Enrique, we’re up against here.

Feck it, let’s actually have a title challenge next season.
 
I’m a big fan of sports analytics and deeply trust baseball's Sabermetrics, but I find it hard to buy into this whole "Amorim vs. Carrick xG comparison."

1. The sample size is too small.
Amorim had 21 games, and Carrick has 16. In serious analytics, aren't these considered micro-samples? How can we reliably identify a genuine statistical trend or judge a manager’s tactical superiority based on such a small sample size?

2. How do we account for the heavily skewed sample composition?
With a sample this small, shouldn't the schedule be nearly identical to make a fair comparison? Look at the bottom 3 teams (Wolves, West Ham, Burnley). Amorim played them 5 times, while Carrick only faced them once. On the flip side, they both faced Top-5 sides 4 times each. If you replace a home match against Wolves with an away match at Arsenal, can you really expect to get a roughly similar xG number with such a small sample?

To me, this looks more like a narrative-driven cherry-picking of data rather than an objective statistical analysis.
 
Before this you saw: Frank, Howe, Iraola, Glasner
Nowadays you see: Iraola, Glasner
Being mentioned all the time

By next year maybe only one name left. Dont know why people like them so much

Very well said. To build on your point about serious analytics, there is a massive issue with how people treat xG as the "ground truth" without understanding how it actually works.

First, "xG" is not a singular, standardized metric. Every data provider uses a completely different model with different variables. Before anyone uses xG to claim tactical superiority, they should at least clarify which model they are using and acknowledge its specific limitations.

Second, football xG models are still incredibly young and carry huge margins of error compared to baseball's Sabermetrics. Confidence intervals are often completely ignored in these discussions. Claiming something like a 0.34 xGD is better than a 0.32 xGD over a handful of games just shows a fundamental lack of understanding of what statistical significance actually means.

So I would like to see some data collating how different managers consistently over- or under-perform their underlying statistics - and what does that say about particular play styles. Not necessarily the sustainability of one play style over another.
In the short term there's plenty of swings for and against the data, but over time it normally evens out fairly well. Not perfectly, but I think it'll be rare you see a significant over-performance or under-performance maintained over a significant amount of time. A couple of years ago I went back about 10 PL seasons and looked at how many teams were significantly different than their expected amount of points, and while every season there would normally be one or two teams that over or under performed by 10-15 points, I don't think there was ever a team that did it season on season. They always returned to a more normal expected point total, indicating that the season that they had been different than their stats was an outlier and not something that could be expected again.

As an obvious case, plenty of people were saying similar things to your post during the first half of 23/24. All the data and stats were saying we should have been down around 14th or 15th, but we were somehow in 6th at that point largely due to opposition teams messing up a lot of good chances (much more than normal). Then from around the end of January if I remember correctly until the end of the season our results started matching our performances and based on that period we actually would have been 14th. Then the following season started and we were in 14th when ETH was fired.

Just now I had a quick look back at the last six years in the PL, and I didn't find a single team that had a 10+ point swing in consecutive seasons which might indicate it was something that team was doing that wasn't being shown in the stats. The closest I could find was Aston Villa who have outperformed significantly in two out of the last three seasons.

I think xPts completely falls apart for basically every side but those right at the top (or those few occasions that the teams right at the bottom have been particularly shit). It basically shows you that the best sides are consistently good at playing in a way that wins points, which is incredibly obvious.

It's too tight in the middle (and that basically starts at the teams challenging for the CL places) to accurately predict anything else, so while the points swings might not always be huge, you can still get fairly large variance of "predicted" position.

Its reliance on xG to build the model means it doesn't take into account the important ability to simply grind out results in tight games that's often the difference maker between the teams chasing Europe and those that just finish 9th-15th.
 

Im sure he also has enough connections in the world of football who can serve as better examples on how to be a manager.

- A failed Valencia manager who was friends with the owner (35.7% win rate)
and
- A failed manager (and assistant manager) who was only interesting because of his hobo beard and not his managerial skills (38.67% win rate as manager)

Are not good examples. They managed much smaller clubs in the terms of pressure and failed spectacularly anyway. However they managed to gain publicity back by becoming a pundit. If Carrick did as bad as them their eyeballs wouldve popped out. The hypocrisy. They dislike Carrick because he is in the position they wished to be in.

Amorim wasn't better in the surrendering positive positions and falling to pieces late in the match measures but it seems Matt doesn't wanna mention that.
 
Outside of the emotional reactions to data, the key thing is none of it matters for next season. Same as those who got hung up on Amorim's first season.

The only thing that matters is what prep we do over the summer and how we start next season.

I have my doubts about the 4231 style we play ever working to the level we need but we don't really know that's how we'll play next season. Time to just wait and see what Carrick can produce with a summer of planning/training.
