Amorim has not been in this team for long, it is indeed disappointing when he can not quickly fix the team, but on the other hand, it seems unfair to immediately label something bad to this coach without giving more time. He came with a very messy team condition, he had to put the puzzle together one by one.
Yes it is true that Amorim has had tough start with team and it is disappointing. But it is also not fair to criticize him too much without giving him enough time to show what he can do. He took over team that was in mess and has been trying to fix it and make it work better. In my opinion it is reasonable to give him another season to show what he is capable of. But if he still can not make things better people in charge should think about whether they want to keep him and they should look carefully at how team does in each match. We will just have to wait and see if Amorim will get another chance next season.
Whoever attacks Amorim for Man U's underperformance this season is ignorant of management and reaching an objective. It takes time for players to get used to a fresh coach's terms and routines. If he leaves the club the new transfer decisions he's made would fireback and the club will have difficulty progressing well next season. The administration is indecisive by changing coaches like clothes.
