8. Iker Casillas
It’s almost unthinkable to imagine the Spain captain in a club shirt other than Real Madrid’s but Casillas has been number two at the Santiago Bernabeu (at least in league games) for nearly two seasons, and he cannot be happy to continue sitting on the bench. The 32-year-old has made nearly 700 appearances for Real but he could seek pastures new this summer. Both Arsenal and Man City have been linked with the World Cup winner.
