Real Madrid midfielder Sami Khedira has refused to set a date on his comeback from a serious knee injury.

The German international suffered the damage while on international duty last November. At the time, it had been suggested that he would miss the remainder of the season and the World Cup this summer.

However, Madrid boss Carlo Ancelotti recently claimed that the central midfielder would be fit to return to first-team training "in 15 or 20 days".

"I tend not to look too far ahead or think about the future; my daily routine consists of an intensive workout – that's all that concerns me right now – not speculating when I might return," Khedira told the German Football Federation's official site.

Khedira had previously been linked with a move away from Los Blancos before suffering the blow.
