6. Paulinho | Tottenham
Brazil international Paulinho cost Tottenham £17m - which, in fairness, was a perfectly reasonable price for a player who had often been compared to Frank Lampard.
But the 25-year-old has wasted so many great opportunities to score this season - he has netted one Premier League goal, when he ought to have at least five to his name - while he has provided a mere two assists.
Paulinho is a decent player, so Tottenham need him to start converting chances on a more consistent basis.
