I still have faith in Aubu; he was performing admirably under Tuchel before his dismissal caused the entire team to fall apart. Letting Aubu go would be another terrible decision given that the team currently lacks a natural striker. Aubu is a good finisher with pace; what he needs is a coach who has plans for him and who can make the midfield work. I just hope that whoever the new manager is includes Aubu in their plans for the coming season. He can still play top football for two years, Xavi wants him back, but the decision will be made by the new manager. The only good and ideal successor if they decide to let him go would be Osimehn, but I doubt he would leave Napoli for a team without a UEFA competition next season.
I can’t wrap my head around what the problem is with Aubameyang, before he moved to Barcelona he could barely score a goal to help Arsenal but started scoring at Barcelona. Maybe he has a attitude problems in the locker room that makes him have problems with clubs he play for.
If you ask me, I would say that defense is much more important these days. We have seen recently when Varane was out and they needed Maguire again, they started to suck right away, it's just obvious that he is not a player for this level and he needs to leave. That means they need to get a great centre back and should be doing a lot better and should be getting better at striker as well.
This is why I believe during summer window they will get one CB and one ST and they will be much better next season. They already did a decent season this year, not amazing but better than last year, with more additions to the club they are going to be doing much better as well. Should be a season to wait for United fans without a doubt, could be even better.
