1 Not sure I agree with 1. I don't think the players got too much power. Maybe Pogba, but I don't feel like it should be a massive problem.
2 Fair enough we got plenty of those. Not sure it is a culture, but some of them might not care much like Sanchez and Martial. Some want to leave De Gea, Pogba, Herrera this season. Others are just past it like Matic and Mata even if they try. The players probably talk more about spending the money they get than about football in private.
3. Hard to know, but I get the impression that the atmosphere post Mourinho have been good. I don't think it is a big factor. Although like I said before they might focus too much on things outside football.
4. I do think we lack driven player to fight even when things are going wrong. It often feels like some of our players give up in games and they drop confidence very easily.
5. We could need more players that inspire and push the players around them to do better. Herrera is probably the only one that had it.
6 Totally agree if you talk about Ole (well do not think the board cares at all)
7 Totally agree if you talk about the Glaziers and Woodward.
8 I do think we got some talent around. Just most of them do not seem to develop or get the best out of it here.
9 I think some of our players do not look enough at themselfes. Focus on what they can do to improve and it goes together with the drive part. Us fans are also far too harsh and it might infect the players. Although we see the same in other clubs.
Fair response although bear in mind I just rattled off a list in no particular order of possible factors to a greater or lesser degree.
To expand on each one in a bit more detail:
1. Player Power
I think player power is definitely a thing with our squad. There's the 'direct' power of situations like the player you identified (Pogba) - think of how the bust up between him and Mourinho was handled by the club in comparison to Beckham and Fergie. There's also the 'indirect' player power - the events of the past 7 years have presumably demonstrated to players that if on field expectations aren't met, most of the blame will be shouldered by their manager rather than them. We've also undermined our managers and given clearly sub-par players nice new contracts and haven't shipped out players that are clearly earning more than their on-field performances/ability warrants. I think the effect of all of this has been to establish a player culture where mediocrity will be tolerated, your primary worth to the club is your marketability and if you don't like the manager, don't worry - they will eventually be gone and a new one installed.
2. Mercenary Culture
The Sanchez transfer was key in this regard. We blew our existing wage structure out of the water for a player we didn't really need who ended up contributing virtually nothing on the pitch. Post-Fergie we've always paid players too much in comparison to their worth as footballers (look at the wages of the PL's best performers like Mane, Eriksen, TAA, VVD, Robertson, B Silva compared to our equivalents like Lukaku, Shaw, Young, Pogba, Mata etc), it is presumably a by-product of our recruitment being so poor and us being a less desirable location for players - we have to pay above the odds to get players. You imagine in the 90s or 00s and it was Ferguson personally meeting prospective transfer targets and their families, a lot would have been happy to sign right there and then for a bag of peanuts and some Quavers. But I assume the Sanchez situation will make this far worse. I imagine the first line that comes out of any agent's mouth when negotiating contracts with Richard Arnold is 'my client contributed far more than the player you are currently giving £500k a week to, let's talk numbers..'.
3. Poor dressing room atmosphere
It's all speculation as we don't know what goes on in the dressing room, but there seems to be a total lack of the sort of strong characters who we know were big dressing room presences in past successful squads. The fact that our official captain doesn't speak English and our normal captain is an over-the-hill winger turned fullback who is frequently the worst player on the pitch (therefore doesn't really have a leg to stand on / any credibility when telling others to buck up their ideas) are signifiers for me. Added to this, none of our players really seem to enjoy playing for United. It seems to either be a chore they aren't particularly bothered about (see Pogba, Martial, DDG, Fred, Pereira etc), or something they dread to the extent they become terrified of making a mistake (see Young, Shaw, Lukaku, Rashford, Jones, Fred again etc)
4. Lack of morale
Agreed mostly for the reasons above
5. Lack of leaders
Agreed.
6. Lack of a distinct philosophy/style of play
Ole is an example, sure, I don't think anybody knows exactly what style of play he wants to implement (besides outrunning your opponents), but he's just the latest example. We've lacked a coherent style of play since Fergie left (and arguably even in Fergie's final few years, although given Fergie was basically a DOF, head of recruitment, head of the academy, head coach and manager rolled into one, I can forgive the club for not addressing it until he left...). It's one of the reasons why we have such a squad of misfits assembled by 4 managers for 4 totally different styles of football. You either need to believe in a manager's vision and see it through to completion, or have a competent executive structure so that the footballing philosophy stays the same regardless of who the head coach is at the time, and if you sack your manager you replace him with another good fit for the overall philosophy.
7. Lack of any short/medium/long term plan, vision or goals
Yep - this all comes from the owners and the board. Clubs like city, Juve, Barca and PSG have the clear aim of winning the CL. Liverpool are clearly trying to do everything they can to win the PL. Spurs, Dortmund, and Ajax are (/were, in Spur's case) operated under the model of signing and developing young talent, some of whom they expect to sell on for far more money which can be reinvested in finding more young stars. With our owners it's not at all clear. They talk in vague terms about 'wanting to see the club as a commercial and footballing success', but Woodward loves reminding shareholders that we've had brilliant commercial results despite terrible on field results. We all know that it's easy to read between the lines and judge their actions / inactions and conclude that they don't really care about the on-field performances beyond qualifying for the CL moneyspinner and staying relevant enough so that 'the brand' doesn't suffer, but they even lack a clear plan of how to do this. They change managers when the fanbase turns on them, spend money on transfers like (inconsistent) drunken sailors with no real thought process behind the sorts of recruits they are bringing in.
8. Lack of talent
I agree with you that we have some talented players. I also agree that another big problem is that lack of coaching / development of talent at our club, so our promising players seem to stagnate. However, I think we do lack a lot of talent compared to our supposed rivals like city and Liverpool. I think we already have the least talented squad in the top 6 (whatever that means), and if we lose Pogba and De Gea this summer, I think you could make a strong argument that Wolves and possibly even Leicester have a better first XI than us. That's pretty scary.
9. Culture of scapegoating/blame among players and fans
It happens at other clubs too, you're right. Real Madrid fans are far less forgiving than we are for bad performances and there are of course other teams who's players seem to turn on each other and blame each other as well.
However, it's one of the most noticeable differences between this squad and our great teams of the past for me. I'm lucky enough to go to most United matches and although this might sound like pop-psychology, whenever something goes against this team, the whole team seem to indulge in this blame game where every missed pass, lack of a run or losing the ball causes one player to blame the other. Pogba is probably the most noticeable player but they all seem to do it. There's nothing wrong with reminding a teammate to buck their ideas up, but with this current United squad it seems to be a way for players to air their individual frustration rather than to ensure team standards are kept high. What follows is usually this weird atmosphere of some token encouragement but mostly silence and players nervously going through the motions. Again I might be reading into this far too much, but it just seems like United isn't a very fun team to play for at the moment and the players go to pieces and resort to blaming each other as soon as the slightest thing goes wrong.
