Since you know that it wi take some seasons for Amorim to win a title, that's the reason why Amorim needs good and professional players like Osimhen who he can work with so that they can both put United back to their glory days.
If Amorim can get the players he wants ASAP, I believe that he will do his job perfectly and we would see a new Manchester United. Osimhen is a player that loves playing with passion for his club and that has always paved way for him in scoring goals.
If United wants a change in a short time, of course, the club must support the program desired by the coach. bButmaybe United have some considerations for their finances. But if Amorim intends to get Osimhen, I don't think the club will lose. Except with what Ten Han did, some of the transfers that were made were not successful enough.
Amorim must have seen the performance of his players and saw some parts that still need to be strengthened. In this case of course there will be players who leave and some will come. Napoli asked very much for Osimhen.
A party's status will not change in a short period of time. Manchester United have underperformed in the last few seasons so whoever takes over as the new manager of Manchester United will have to give time and if he is given financial freedom he will surely be able to mold the team to his liking. Since a manager is the mastermind of a club, better team performance is obtained if he arranges the team according to his wishes. After taking charge of Manchester United, this manager has not had much time to implement his strategy, but based on what kind of strategy he is applying in the upcoming matches, we can get a clear idea about this manager. But I can say that this manager will definitely do better for Manchester United than the one who was in charge of Manchester United before.
