Demba Ba - Chelsea - £7.5 million

Daniel Sturridge - Liverpool - £12million

Sturridge started his career at Manchester City and then moved on to Chelsea and four years on the England international got limited chances with the Blues. A loan spell at Bolton Wanderers in 2011 helped Sturridge to prove that he can play at highest level. He scored 8 goals in 12 matches for Bolton. The 23-year old striker already has three goals in four appearances for Liverpool.
