7. Fabio
Both he and twin brother Rafael were set to be a part of the new wave of talent at United, however, where the man on the right has excelled Fabio has stuttered.
Having spent the majority of last season on loan with Queens Park Rangers, he is behind Rafael in terms of development by some 60 appearances and it seems as though he would be best served somewhere else. Still a capable full-back with a lot to learn, he is perhaps not what United need right now, but there is no doubt that he will have an accomplished career away from Old Trafford.
