Sami Khedira (Real Madrid)
Perhaps the most sought after of all the players whose contracts run down in 2015 is Real Madrid midfielder Sami Khedira, with the World Cup winner yet to agree a deal to stay at the Bernabeu. The German international is the kind of dominant, box-to-box midfielder who Arsenal have lacked for some time and, if they can agree a wage packet with Khedira, he would be likely to prove the perfect buy.
