Sami Khedira (Real Madrid)
German international missed most of last season and could well become surplus to requirements given the number of central midfielders Real Madrid have on their books.
The likes of Asier Illarramendi, Xabi Alonso, Luka Modric and Casemiro are vying for first team slots and the former Stuttgart man may well be considering his options this summer.
The tough tackler could well be the ideal replacement for veteran Mikel Arteta, with the Spaniard having a fairly average campaign and has just a year to run on a contract that may well not be renewed.
