The Real Madrid ace was initially ruled out of the competition after sustaining an injury, but could make a shock return in time for the final on Sunday.

This year's World Cup has been full of plenty of surprises, and there could be an even bigger one in time for the much-anticipated final on Sunday.

France, who are the reigning champions, are hoping to become the first side since Brazil to defend their crown, but Les Bleus will arguably face a stern test against Lionel Messi and Co. 

However, heading into that match, France just may have a crucial ace up their sleeves. According to multiple reports, Karim Benzema, who initially was ruled out of the competition after suffering an injury, has apparently returned to training.

The Real Madrid star, who deservedly won the Ballon d'Or this year thanks to his dynamic performances for Los Blancos, looked set to have to miss out entirely after being injured just as the competition was going to kick off. Yet the 34-year-old could be given some game-time as he hopes to add a World Cup medal to his already glittering trophy cabinet.

Naturally, head coach Didier Deschamps has not confirmed or denied whether Benzema will be involved on Sunday, but the fact that he was never replaced in the squad after his injury clearly indicates that France did have some hope he'd be able to recover and play some part in this competition. 

It remains to be seen whether this actually comes to pass, and all eyes will be on the French squad over the next few days as they prepare to face Argentina on Sunday.
