Last season Mason mount didn't play well with Chelsea so it is still in doubt that he could give the best performance for Man United in his first season, the quality of this player is indeed very good but nothing can guarantee Mason mount can recover from what happened in last season with Chelsea.
However, a coach must have known the capacity of a player before being recruited to suit his style of play, Ten Hag has so far made Manchester United much better and the recruitment he made has no doubts, as well as what happened to Mason mount when This.
Ten Hag is just trying to get players for the positions he needs in the Manchester United team and I think Mason Mount is the right man for Manchester United. Even though Mason Mount didn't look any better at Chelsea, because if he had improved himself at Chelsea it wouldn't have been as obvious nor would it have affected the team as much if the rest of the players were as bad as they had been last season. And I'm sure that next season Ten Hag will train Mason Mount to become a better player at Manchester United so that everyone can compare and judge how Mason Mount was when he was coached by more appropriate people in different teams.
