Amorim just needs time but he shouldn't be given the room to abuse it just like Ten Hag did. If Manchester United must grow again as a team they need then Amorim should pay very close attention to the strength of his squad. Note down which player suits a position better, which one can come in as substitute and as well as players he feels he won't be needing.
The goal is to win the Europa and this won't be achievable with the inconsistency been displayed by United. The team doesn't deserve petting they should have rigorous trainings and so they can boost their confidence and return back to their winning streak
Secondly the team need to understand themselves especially on the pitch.
I think Hansi Flick is the guy right. He's a manager that does not play with trainings and doesn't condole any sense of disrespect or ineptitude with players even on the training ground. Oftentimes we've heard players saying though he's a friendly guy but when it comes to discipline he's ground standing.
Manchester United needs such a manager who will take his time to study the gameplay of each player and under the synergy between the team players. Amorim needs to be very prudent in his approach towards handling his players and transfer out players which are not strong enough.
