Manchester United management has changed coaches in the last few seasons so there is no reason to look for a coach and expect instant achievements. Everything needs a process and in my opinion what Manchester United management is currently doing is correct.
Now Ten Hag only needs a few additional quality new players to fill the squad and I think Man United under Ten Hag will be much better next season.
but the problem is that spending large amounts of money but not getting satisfactory results is one of the bad things that a team like Man United will experience, which for me last season spent large amounts but was not able to get satisfactory results and in my opinion even though Ten Hag can still given trust but I believe more that Man United will be more successful after Ten Hag was fired from Man United and try to find a new coach who can make a better contribution through a strategy that can always provide a little improvement.
I don't doubt Ten Hag but for 2 seasons I have tried to believe that Ten Hag can give the best for the team, but next season will be the last season I believe in Ten Hag and if it fails, maybe I will never believe again and no matter how much I will ignore the huge trust of Man United fans because Ten Hag has been given many opportunities and the coming season will be the last season to prove that he is truly a reliable coach.
