6) Mario Balotelli, AC Milan to Liverpool
Not many players have been a flop as much as the 24-year-old. He can now add the Merseyside club to Manchester City and AC Milan to where he has failed to deliver.
5) Mauro Zarate, Velez Sarsfield to West Ham
The 28-year-old has already been loaned out by the East London club to QPR, who have since attempted to send him back according to the Mail. Not a great first season in the Premier League.
