3) Robin van Persie
Not a regular for United so far this season, Robin van Persie’s injury problems may be coming back to haunt him as he enters the twilight years of his career. Real Madrid and Barcelona have recently been linked with the Dutchman, and United may now be ready to jump at the chance to sell him while they can, in an expected £20m deal. This may not go down well with the fans, who have warmed greatly to van Persie since his decision to join the club in a controversial move from rivals Arsenal.
