Fifa is looking into alleged racist abuse directed at France players during their 3-1 win over Russia.
The world governing body said in a statement it was “collecting the different match reports and potential evidence” of the discrimination.
Manchester United’s Paul Pogba and Barcelona’s Ousmane Dembele are said to be among those subjected to taunts.
The match was played at the Krestovsky Stadium in Saint Petersburg, a host venue at this summer’s World Cup.
French Minister for Sport Laura Flessel said: “Racism has no place on the football pitch. We have to act in unison at a European and international level to put an end to these inadmissible actions.”
