Maybe Manchester United really has to change the team on a large scale and start again from zero. Because what I see at the moment is that the Manchester United squad doesn't seem to have good chemistry or chemistry anymore.
Changing the team drastically? Isn't that too much? The club has to spend a lot of money to recruit players and they also need to sell some players if they want to change everything, but I don't think that's a good idea. The club only needs to recruit a few players who really need to be fixed. Amorim needs to sort out the players who are suitable according to him and the players who are not suitable can be removed or loaned to other clubs so that he can build a team that suits what he wants.
In fact, it would be the right decision, another thing is that it is simply impossible for financial reasons. United (like probably any other club) cannot afford to change the team entirely when changing the coach. Therefore, United are expecting targeted changes that will gradually lead to the team that Amorim wants. As for selling/renting players, I don't think there are many options. Who needs Rashford with his salary? PSG were after him before Ten Hag.
