Unfortunately, it seems that Manchester United changes coaches but they all think the same way and make the same mistakes. For example, there is Victor Osimhen who is a very skilled striker, but Manchester United stops signing him and spends a lot of money signing players without great skills. So it is difficult for a team to have good results when they have this bad behavior.
Let's look at the squad of Liverpool, Arsenal, Manchester City, they have players with great skills from the attack, midfielders and defenders. But Manchester United doesn't have that.
I think Amorim will bring about a change in Manchester United. He’s convinced me with his success at Sporting Lisbon, the problem to me is not the coach but the problems lies within the board because I don't know why a team of Manchester United's caliber cannot even make good signings. In the case of Victor Osimhen, I think the reason why he wasn't able to move to Manchester United was given to his high transfer fee which some may say it’s understandable that Manchester United in their current situation are trying hard not to make any expensive transfers due to FFP regulations.
It is not easy for a team that is in a slump like Manchester United to recruit quality players because every player certainly also looks at the percentage of the team to be able to win the title before deciding to join.
Manchester United's management has indeed made several mistakes in recruiting since long ago but for all that they also cannot be blamed entirely because of course every recruitment is made based on the wishes of the coach but from several previous coaches none have succeeded in lifting the performance of the Manchester United team even though they have been supported by management.
For now Amorim has not proven anything so I do not have strong confidence that Amorim can improve the performance of the Manchester United team regardless of his success in the previous team but I think it will be different from handling Manchester United who compete in the Premier League.
