He has shown his skills in a few matches in charge of Manchester United and his match management skills make everyone think that under him Manchester United will do well in the future. Another manager is getting a lot of success by taking over the responsibility of the team that another manager has arranged according to his own mind. Manchester United has been underperforming for a long time and everyone has given up on expecting anything better from this team, but now that a good manager has arrived in the team, everyone may expect this manager to bring the team back to a good level.
When there is a new manager in a club, it raises expectations. We can see from the arrival of Erik Ten Hag for the first time to Manchester United, yes, that expectation arose and hoped that in his hands he could bring Manchester United to success and in the end it ended badly. Now Amorim has come and that expectation has resurfaced. I can't say he will succeed or fail, because it takes time to see it all. Now what can be done is to believe in what he is doing, there is no choice but to believe in the process, regardless of whether it will work or not.
Amorim could bring trophies to Man United, provided the club top brass back him with sufficient funds to build squad depth. It is only natural that fans set high expectations when a managerial change occurs, they hope for a change for the better, especially since Amorim has an impressive track record when coaching Sporting CP. It is true that everything takes time, there is no instant success, Amorim and his players must go through all the stages and overcome every challenge. If Amorim fails to bring trophies this season, I think we cannot blame him entirely. The opportunity to win trophies is still open, and we will see if Amorim will succeed.
