Amorim joined Manchester United at a very wrong time, he was signed to bring glory back to Manchester United when Ten Hag has already ruined the team, it is becoming difficult for him at this moment because of the standard Ten Hag set before leaving which he need to put extra effort before changing to a better pattern he is used to.
On the contrary Amorim did not joined Manchester United at the wrong time because he is not the first coach to join a club at there difficult moment, however would you mind to explain why you believe he joined Manchester United at the wrong time so that I will have the overview on why you think so, perhaps would you also say that Ten hag joined Manchester United on the wrong time?, actually we don't have a wrong time or good time in terms of coach joining a club because a club can be very okay but the moments new coach is signed it became worst and some worst club become strong after new signing, so actually the view of joining the club at a wrong time shouldn't be justification of his inabilities.
