This is the only season and chance he has to prove himself, while he was handed over Manchester United as the head coach mid season, Erik ten Hag records at the beginning was narrated as reason why he didn't perform too well but time around he is getting new signings according to his game style and everyone are watching waiting to monitor his progress.
Preseason are just friendly, nothing much to be excited as teams are using this games to try out new strategies if its fit to impact in matches when the season starts.
This season is not just a pressure for Amorim but for other teams especially Arteta. Although Amorim is more serious especially after finishing 15th on the table last season. He has gotten a better attacking prowess with the recent addition to the team and hopefully they can compete, and we may know if he is the right one for United.
The matches that are played now, from pre-season, are just friendlies, nothing exciting
Furthermore, these are matches that make little sense, given that many coaches experiment with things they otherwise couldn't do.
different modules, different formations, different strategies
things you can't experience in the league or cup
so there is no point in considering them
For some teams, preseason matches are crucial, especially a team like Manchester United, which is seeking its best form. Preseason matches provide an opportunity for Ten Hag to try out some new tactics that work for him. However, we can't judge their achievements in preseason matches; this is simply a chance for the coach to find his best form.
Frankly, I'm very pessimistic about Manchester United's performance next season. This is because there hasn't been any visible change since Amorim took over, and they haven't made many changes to oversee next season. Therefore, it's highly likely that Manchester United's performance next season won't be much different from last season.
