although he still occasionally plays for Ten Hag, this season he has been mostly on the bench. Ten Hag already has important names at the back. maybe it would be good for him to leave Manchester United for his career. but in my opinion, he will stay there for some time. look at his contract which is still long. there are still many other options for MU to play him when the backline is experiencing injury or card accumulation problems.
There was one game once and it wasn't long ago I forgot which team Manchester United played against, there was the name Harry Maguire, but Ten hag instead put Luke Shaw at center back and I don't think that makes sense, then Tyrell Malacia became left back. But seeing the current condition of the Red Devils it seems that the option to stay is quite good for Maguire, even though he will not be included as a substitute later, maybe it is better for him to immediately correct what is wrong with him and Ten Hag can give him confidence again.
Maguire is a player for England's main national team and it's been a while since every English player has always been the priority at Manchester United. But the arrival of Erik Ten Hag was considered brave so not a few of Maguire's matches were postponed. In contrast to other coaches, before Erik Ten Hag at Manchester United, Maguire performed poorly and was always used as the main player. So I saw a firmness in Erik Ten Hag, he really controlled Manchester United for the sake of mutuality. Moreover, even if Maguire leaves, I don't think it will have too much impact on the stability of Manchester United's game.
Indeed, the previous coach Solskjaer spoiled Harry Maguire too much, even though everyone and fans also knew that his performance was very bad, but Solskjer still insisted on making Maguire the main line-up. But indeed, after all control is held by Ten Hag he will not hesitate to all his players, whether they are senior or young, all get the same treatment, this is all for the good of the team and not for just one person.
