Manchester is a team that are in big problems, they have been in big problems for a very long time now and I am now thinking it's more than coaching problem. Manchester United may also have some internal problems from the owners and this can cause a drop in form as we have seen .
I think a lot of improvement needs to be made and it starts now. Manchester United can't continue going to every season with this problem, they have lost the pedigree of a big team and this has affected their mentality.
United have become a breeding ground for talent long before this season and there has been no talk of any champion mentality for a long time. Maybe it’s just time to come to terms with the fact that others have taken its place and now in order to even just return to the top 4 (stable and not randomly like last season) infrastructure changes are required (the need for which, by the way, Ronaldo spoke about in his famous interview). United has partially changed its owner, maybe we will see some serious changes, but I think they will happen by the summer.
It is unfortunate that Manchester United has become the talk in football and not only this season but from like several seasons after Alex Faguson left the club.
