Real Madrid striker Karim Benzema could make a shock appearance for France in Sunday's World Cup Final.

Rumours swirling that the Real Madrid forward is flying back out to Qatar.

The Ballon d'Or winner suffered a thigh injury in training on the eve of the World Cup and was expected to be ruled out of the whole tournament.

But France did not call-up a replacement for Benzema and he is still officially registered in their 26-man squad, so could play a role against Argentina if he has recovered, says the London Evening Standard.

Benzema has now returned to full training with Real Madrid and, according to multiple reports in Spain, could return to Qatar after France set up a final against Argentina.

France coach Didier Deschamps refused to rule out a shock return for Benzema after the 2-0 win over Morocco on Wednesday night, saying he "prefers not to answer" when asked the possibility of the 34-year-old re-joining his squad.

After closing his eyes and puffing out his cheeks, Deschamps said: “I don't really want to answer that question." He then smiled and said: “Next question."
