Mate, if all you understood when talking about criticising players was "I don't like him" then we don't have to talk further. Of course all those things are connected and of course we have to trust Ineos to do their job BUT again - this is exactly what we did all those last years - put all our hopes on the next guy to suddenly find a formula how to get something out of that miraculous squat that is Manchester Uniteds. And then it gets "clean slates", every manager "needs to assess his options" bla bla bla. Exactly that is the reason, why we still have players like McTominay or Maguire.
The next manager will face more or less the exact same conditions here - we have a 10 player in Bruno who for all his qualities has a limited skillset, not really suited for todays 10 slots. We have McTominay who has no real upside apart from being tall and physical and having a knack for appearing in the box, can't really play midfield though. We have Mount who is rather lightweight but probably the closest thing to a modern day 10 player, we have Mainoo who is a modern player that probably works well as soon as he gets somebody next to him to take over defensive responsibilty and we have the ghost of former Casemiro. Now go, work out a combination that creates a functional 2024 midfield with that. Considering our Fullbacks are decent to good overall but don't really contribute anything to an attack. Add a backline that consists of big Harry who is a sloth, timid Victor, injured Varane und Tiny Martinez who is really good on the ball. And add an attack consisting of inexperienced Hojlund, a Rashford who is made to think he is the reincarnation of late Ronaldo while not even being very good in dribbling and can't be bothered to work for the team.
As a combination, this is a mess. Naturally, there is a case for every player to be made. But for some it just doesn't make any sense to continue trying to hop around the inevitable. Yes ETH failed the team this year with insisting on his system change. But a system change is inevitable! Eth just didn't do it very well and he didn't cope with the adversity he had to face.
After all, it is all just opinions and all and obviously, I am not able to predict the future better than other posters can but I am sure, as long as we keep dragging those problems outlined above with us, we will not turn into a noteworthy team. The players were left off the hook too many times and too many false dawns have been lauded falsely (like last years league result) and the wrong conclusions have been drawn ("we only need this and that player to compete") - I see only one way, prepare to create a team that will compete in three to four years. That is the best we can do. All attempts to somehow get the best out of what we have right now are doomed to fail and will end in us failing in every aspect - ending with no short-term success nor with a team that is able to compete in 3 to 4 years.
