7. Koke (Atletico Madrid)
Despite being strongly linked with Atletico Madrid striker Falcao, Chelsea would do well to look at his team-mate Koke, the latest in the line of talented midfielders being produced in Spain. The 21-year-old has lit up La Liga with his displays this season, and a Spain call-up is surely not far away for the youngster. Koke would provide a decent alternative to the likes of Ramires and Mikel further back in Chelsea’s midfield, and would link up well with his fellow countryman Juan Mata.
