France have filed a complaint to FIFA over the decision to disallow Antoine Griezmann's late goal in Wednesday's shock 1-0 World Cup loss to Tunisia.

Griezmann thought he had cancelled out Wahbi Khazri's strike when he volleyed home in the eighth minute of stoppage time at Education City Stadium.

However, after the celebrations had died down, referee Michael Conger ruled out Griezmann's goal for an offside infringement.

The Atletico Madrid forward was adjudged to have been offside when firing in from Aurelien Tchouameni's pass, which took a deflection off a Tunisian defender.

However, the French Football Federation (FFF) believe the officials were wrong to disallow the goal as play had already restarted when VAR intervened, which is prohibited.

"We are writing a complaint after Antoine Griezmann's goal was, in our opinion, wrongly disallowed," said a widely released statement from the FFF on Wednesday. 

"This complaint has to be filed within 24 hours after the final whistle."

Khazri's superb strike at Education City Stadium ended reigning world champions France's nine-game unbeaten run in the competition stretching back to the 2014 quarter-finals.

However, the result ultimately meant little in the context of Group D as France still went through in top spot and Australia claimed second place with a 1-0 win over Denmark.

Should France be successful with their appeal and the scoreline is changed to 1-1, the final points tallies in Group D will change but not the positions of any of the four sides.
