Professional players should be able to adjust to whatever conditions it is. Maybe a big win is not a guarantee that the team will be good there is gambling in every decision. But indeed it must be taken. Amorim came and started his way to get cohesiveness and mental strength. Maybe at the moment it hasn't been seen and Amorim is fixing it. Amorim could also take advantage of the winter transfer to add to the team's strength, and that's what I think should be done. Let's take a look at Amorim, what will change after the transfer market.
Now it seems that the problem is no longer with the coach because there have been several coaches who have handled the Manchester United team without any significant changes, Amorim is certainly a good coach but we see how the Manchester United players in their last match seemed unable to play for a solid team, as is true and I agree it would be better for Manchester United management to overhaul the entire existing squad, as Chelsea did 2 seasons ago.
There is no one to blame, currently Manchester United is not in a good condition with several great coaches coming but no changes have occurred at Manchester United. Amorim is a coach who has had a good career so it cannot be said that Manchester United's weakness is in the coach because Amorim has to manage game with the existing players. I think the overhaul of everything is very suitable, starting from management and all the players, that is the only way Manchester United can return to glory.
