4. Juan Mata
The Expectation Mata was a huge points scorer last season, and was at the heart of most of Chelsea's best play, pulling strings from the middle of the park and scoring 12 goals in the league. His form was particularly valuable for a team lacking a 20 goal a season striker, and still reliant on Fernando Torres to shake off the shackles he appears to have been so limited by since his big money move from Liverpool. Ahead of the start of this season, Mata was reassuringly expensively, reflecting his worth to his team at £9.9 with the Premier League's game, the same value as Arsenal's Cazorla, and more than Yaya Toure, Steven Gerrard and Michu. He should have been great this term. The Problem Last year's third highest midfield points scorer (according to the Sky Sports stats,) Mata isn't enjoying the same sort of season as he did last year, thanks to his inconceivable drop out of the first team picture under new boss Jose Mourinho. With rumours circling that the Spaniard almost found himself out of the Premier League entirely (or at least at another club,) it doesn't look like Mourinho's claims that he still values the player as part of the first team hold much water. Strictly speaking, Mourinho is to blame for Mata's lack of form and points, but that won't be much solace for those who were sucked in by last season's form and the reassuringly high price tag.
