Ten Hag has been so poor in handling the dressing room, he has a problem with player management and i don't even know what his footballing philosophies are, he is an average manager at best and he'd prolly go in the summer.
I think firing the coach is not the solution for Man United at the moment, look Man United has had several world class managers and all of them have failed at some level. The problem is that there is a culture at United where the players are bigger than the manager and the board/hierarchy plays into that.
There needs to be a cultural change where the manager is seen as the ultimate boss and instills less fear in the players. Once the players are afraid of making mistakes, that's how Man United will start to see good results. Man United in the UCL league doesn't need to expect much this season, I predict they will remain in fourth place as bottom, qualifying for the last 16 of this group. Bayern Munich is accompanied by Galatasaray.
In my own opinion, I think that best thing to do now is for the Manchester United heirarchy to sack Erik Ten Hag and hire a manager that'll establish good relationship with the manager while bringing out the best from the players.
