Amorin is simply trying to improve Manchester United using his own experience and abilities, but the team management must also fully support his efforts to produce better results than last season. And from the players Manchester United has already acquired, I believe they are very serious about developing Manchester United into a better team. So next season, we might all see a different Manchester United team in terms of performance in the Premier League, although I don't expect them to immediately become title contenders.
I'm sure Man United management will support whatever the coach decides to do. Unfortunately, the events of last season, including the bad times under Ten Hag, may make management a little more cautious about giving the current coach freedom. And when it comes to improving performance, it won't happen overnight, and Amorim needs time to make significant changes. The EPL is incredibly competitive, and it's no easy task for a coach. Man United needs more quality players to compete for the title, and that won't happen this coming season.
Those players that was bought expensively would be sold first before United will have the flexibility to buy the players that will replace them to improve the team performance. If those players did not leave the club, it might be difficult for us to see a significant change in the team performance because they are too weak to meet with the task expected from them by the club and fans.
