1. Iker Casillas | Real Madrid
This time last year it would have been inconceivable to imagine that Iker Casillas could potentially leave Real Madrid.
The veteran Spain goalkeeper is, or at least was, Mr. Real Madrid.
However, he might need to leave the Bernabeu in January in order to cement his place at Spain's No. 1, on account of the fact he hasn't played a single La Liga game this season.
Although he's been playing in the Champions League, Casillas desperately needs to play league matches over the coming months.
