5- Iker Casillas

United and Arsenal have both expressed and interest in the World Cup winner, and put plainly, if he was to be made available there's only a few teams on the planet that he wouldn't walk into.

Ancelotti is keen to keep things civil with Casillas and has promised him the opportunity to prove his worth in European competition, but it might not be enough to stave off the idea of a January move with Brazil 2014 on the horizon.
