A Tottenham supporter here but I'm going to say although Fellaini isn't worth £27m he will improve. He's a good player. He plays well CM for Belgium but I don't think he's good enough to be a regular at United. He will improve I'm sure but right now he plays like he's very nervous and he's trying to hard. I think the pressure of being at United is getting to him.
I remember when he first went to United he was talking about the difficulties he's faced with the intensity in training. Maybe he won't ever be a quality CM for United but I definitely think he'll improve. But it'll probably be next season when you see his best when he's had a proper pre-season. If he doesn't improve and folds under pressure I can see United trying to sell him summer 2015.
And he isn't your worst signing. Bebe the worst, easily. What was it £7.5m? FFS.
But I think you lot will need two new CM signings. Carrick is getting older, Cleverley is average, Anderson needs to leave, Fellaini needs to improve, Giggs will retire at the end of the season and I think Jones will be a Cb long term. I think United should go for Cabaye or Rakitic in the January window then a top quality CM in the summer.
