3) Marouane Fellaini (£15m)
Recent reports suggest that last summer’s major signing from Everton, Marouane Fellaini, could already be heading for the Old Trafford exit after a highly disappointing first season with the club. The Belgian international had been one of former manager David Moyes’ top transfer targets for some time as he was desperate to raid his old club to bring him to United, but the £28m signing flopped spectacularly, making just 21 appearances in all competitions and failing to register a single goal. The 26-year-old could now leave for almost half of what the Red Devils paid for him, with a £15m asking price seemingly being agreed by the club.
