1. Emmanuel Adebayor
A loan spell at Tottenham looked to have breathed new life into Emmanuel Adebayor after a bad time with Manchester City, but since joining Spurs on a permanent basis he has looked like being a waste of money yet again. In and out of the team under Andre Villas-Boas, the Togolese frontman has just three league goals this season. He and Jermain Defoe struggling for goals has put a lot of pressure on Gareth Bale to deliver the goods, and has given the Spurs manager a real headache in the transfer market this summer.
