Chelsea & Man Utd stars among 12 players clubs MUST keep hold of this summer, plus Raheem Sterling

11) Koke (Atletico Madrid)

A player with a big future, Atletico Madrid would do well to hold on to Koke for as long as possible despite big interest from Chelsea.

12) Diego Godin (Atletico Madrid)

Another of Atletico’s stars wanted by bigger clubs, Diego Godin has been linked with Manchester United and would leave a big hole in Diego Simeone’s defence.
