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
The purpose of preseason matches is to prepare all aspects of the team so that positive changes can occur ahead of the actual season, especially in terms of strategy and the observation and evaluation of players, both existing and new, which is crucial for the coach and carries a significant responsibility for the club.
While friendlies or preseason matches are not serious matches, they are crucial in preparing the team for the real competition. Nothing is more serious than the first match, as it demands a strong performance from start to finish, and friendlies or preseason matches are the best time for that.
