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.
Yes, although Manchester United have managed to get a few wins in their last few Premier League matches but that's not the end of it, they still need a lot of adjustments in terms of balance to restore consistency in performance. I honestly don't know what Ten Hag will do but there is certainly no time for him to relax in the midst of a team that needs a lot of changes. Changing the scheme and tactics of play may be one of the actions that need to be taken, I hope Ten Hag will know what the real problem is with his squad. Yes as the transfer window reopens this season then it might be a good opportunity for Ten Hag to look for some candidates who can help in the change of his team, and also yes I think the main point is that somehow Ten Hag must change the game scheme, try some actions to restore the consistency of the squad. There are only a few games left towards the end of the season and I hope Manchester United will be able to climb back up at least into the top five of the table which is still pretty good.
