Manchester united problem is something else because they have continued to change players and coaches since Fergie left the club but all to no avail. It's quite sad to witness a once giant of the game even at the world level to be so belittled by so many little teams because I believe if Manchester united were in good shape, crystal palace would never had won that game with such huge margin.
The lack of inconsistent is part of the Manchester united problem not the only the players and coaches that they like changed at any time they wish to. Because if we look at the their performance is not something that is straight forward, how they perform in some of their previous matches well this not how they are performing now honestly.
And one thing I always observe about the Manchester united when they come to meet with the big team they will make sure that they hold them well and win the match or lead the game to the draw, but if it's a weak team that people will ne expect a good outcome from them is that they will fuck up the same thing to thier yesterday match against crystal palace. Their next match is against Arsenal again which another double pressure, because I don't think they will have single goals against arsenal.
