1. Diego Costa – Atletico Madrid
Atletico have virtually resigned themselves to losing the striker this summer as his goalscoring exploits continue to earn him admirers in every division across Europe. Chelsea have been the club most recently linked with his signature, and Atleti have even intimated that they may be prepared to let him go for just £27m. If this is the case then Arsene Wenger should move to bring him on board as soon as possible.
