Love Ole the player, person, and manager, even if as he himself admitted, couldn't take us to the next level as a manager. Listening to him talk about his time at United is why I am not quick to criticise ETH currently and was never as reactive as some of our fanbase towards previous managers like LVG, Jose, Ole. He highlights how terrible this squad really is/was - unwilling to take on leadership/responsibility and spineless for the most part while thinking they're better than Man City. Lineker, Alan Shearer and Micah highlighted it recently as well - 95th minute of the City/United game with City actually leading 3-1 and having a buffer, Foden ran right back after an attacking phase to defend a throw-in. Yes Ten Hag has made plenty of his own mistakes but we're still left with a lot of players from those eras, I don't like to get into those specific players of course, because we all know who they are. The point is, we really need to get rid of these players/personalities from our team.
In terms of the alternative coaches being discussed:
Nagelsmann was hailed as one of the good up and coming managers, but lost a bit of credibility after Bayern, and hasn't had enough time with Germany NT to show that he's still a very good coach, maybe we get a clearer idea about him during the Euros?
Tuchel is a great coach imo, Champions league winner with Chelsea and 4th places in that same season but he's also a disciplinarian like ETH that ran into dressing room problems, and is currently having the same sort of issues with Bayern - I like the idea of Tuchel, but given the season he's having at Bayern (currently a lower win rate than Nagelsmann), do we want him here? His current Bayern iteration is also a bit 'moments FC' just like us. Tuchel himself has made plenty of transfer mistakes btw, if we're using transfers as a stick with which to beat ETH.
Flick could be an option and is a champions league winning manager, but is coming off a terrible spell with Germany NT.
Inzaghi is a great coach, but would need a bit of an overhaul here with players if he wants to play the way he plays? In addition, is that conservative style he plays how we want to play at United?
Luis Enrique maybe could do it and I do think he's a superb coach, but I don't know what his future will be with PSG, and whether he'd like to manage in the prem.
While I acknowledge his mistakes, I don't necessarily have a problem with Ten Hag at this stage because since Jose's days, I have always blamed the players more for our performances and not the manager- That is the case for Jose, Ole and ETH and even LVG to an extent. And if we were to go for a new coach I'd be happy with Tuchel, Inzaghi or Enrique - but I suspect all three will end up in the same bin as LVG, Jose, Ole and ETH if we don't fix the player issues immediately.
Ten Hag for me is going through the same pattern that Ole (less vocal about it during his tenure) and Jose (very vocal about it during his tenure) went through, and Ole said that much himself in the interview - for years we've tried to fix this pattern by changing managers, why not try to go about this in a different way now? If Ten Hag is just not good enough after all that, then yeah I think he needs to go - but these changes shouldn't end with the manager imo.
