In my opinion, Manchester united has not changed this season, in fact they have experienced a slight decline in starting the league this season, and it is not surprising because Manchester United itself has not really changed the team scheme while still retaining its old players, so it is not surprising that their performance has not changed either.
Maybe there will be an increase in team performance, but it will take a long time and many matches ahead for a coach to find a scheme that is suitable for a team with limited players.
If Manchester United wants to make significant changes this season with the player scheme and the way they play this season, the coach and the team as a whole must really care about this. Especially they have to take advantage of the transfer market when it opens again this season and also change the way they play slowly so that there are more significant changes for the team, because what Manchester United needs now is to win in every game that remains this season.
Manchester United made many changes during the last few years and this team was not stable at all and maybe that's why they had poor performance even after the summer when Manchester United hired the players Ten Hag wanted to have in this team.
I think the most important reason for us to see Manchester United's poor performance is because of the changes Ten Hag made during the summer while Manchester United didn't need some of these changes
