BOUGHT: Marouane Fellaini £27.5m
From the moment Fellaini arrived it was agreed that United had vastly overpaid for the midfielder, and that was before anyone knew how badly the move would work out. The Belgian cost a huge amount of money, and is on a huge contract. While he has broken back into the side recently, he’s providing nothing that signing for a 10th of the price could have brought to the team.
