The problem actually lies with the players instead of the coach. United has a bad player composition, they got alot of midfielder when what they truly need is more defender and apart from that there are many injuries that strike the team so the coach needs to change the player and use less inexperience player for the match
And they need geniune wingers, because who have they got for width right now? seems like they get stuck with playing a striker or midfielder out wide. United over last 20 years always had decent wingers but when you have ryan giggs i guess it always helps.
