4. Steven Caulker
Andre Villas-Boas deserved to be sacked simply for selling Caulker and keeping Michael Dawson last summer. While the Spurs captain is clearly a top bloke, he has been cruelly exposed by speedy and skilful strikers far too often this season, while the almost-permanently crocked Younes Kaboul is likely to leave on a free when his contract expires this summer. Spurs desperately need some consistency at centre half next season and Caulker, who has been very impressive in a rubbish Cardiff side, would go some way to providing that if he returned.
