Ten Hag is full of luck right now, because in any other year he will be sacked so much early and had no chance of stay in his spot.
But thanksfully for him Manchester United still in the bad moment for so many years, so the management dont want to change again the coach, they tried it before and no one bring any solution to the main problem, so they want now to keep him and give more chance to solidify a project.
It's even looking like ten hag isn't even so concerned about the chances of getting sacked from Manchester United any time, in his statement at the end of the season, he didn't sound remorseful he said he's going to other team to win trophies if Manchester United wants him no more. For a person who have made such statements, obviously he's definitely not going to cares whatever the results are because it's like he's got nothing to loose so he's just going to work at his pass and not what the team is expecting from him. My hopes are on the fact that he thinks to make use of this chance well enough to better Manchester United for the sake of his own career because of he's not getting good results here, I doubt if other teams would want to hire him if he gets sacked.
