The change of coach should have happened at the beginning of this season.
It shouldn't be a problem if club management want to find a replacement coach in the middle of the season just because of a series of bad result the club has experienced.
We see that Manchester United has a very bad performance, at least the change of coach happened in the middle of the season.
If it's the best choice and can improve the team's performance, then I think it should be done. However, finding a new coach who fits the quality of the team is very difficult and it is not uncommon for many clubs to make mistakes because they are too hasty in making choices.
If not, we will see manchester united will always be like this and even worse.
Two Manchester are in the same condition, so if Manchester United have to find a new coach then what about Manchester City who are only 1 point ahead of United ?
I just think that the three matches can't decide how they will move in the next game to the end. Why not give them a chance ?
