Yes, Ten Hag should also have a lot of experience at Man United and really knows the characters of the players there. So he should have done it more easily and quite optimistically. Indeed, this will not be easy but Ten Hag certainly has a strategy to bring his good name back and make Man United, which incidentally has been labeled bad, become much better. So, what Ten Hag will do this season will really have an influence on Man United's results. Of course, Ten Hag must be much more skilled and precise in formulating strategies and also purchasing players. Because this could be Ten Hag's opportunity this season.
It is very possible as you describe, in fact I hope so because I am a big MU fan, but when MU was scary, but now? Now Ten Hag is like that university student who always fails the same subject and always starts the semesters with vigor and ends with shivers, and it is amazing that a team like this always makes the same mistakes, MU management is really in no hurry to keep admitting it, just because they won the FA Cup does not mean they are good, they are not bad either, because when you see the squad they have it is impossible to say something like that seeing the quality of the players.
