1. Diego Costa – Atletico Madrid
Costa has become Europe’s most sought after striker over the past two years, and good news for Chelsea fans is that he’s available, and available for a knock down fee. The Blues also have a massive bargaining chip in the shape of Fernando Torres, who is thought to be keen on a return to the club that launched his career. If Chelsea don’t win the title this season it will be because of their lacklustre strikers and their goal shy performances. With Costa in the side, that will no longer be an excuse.
