MOSCOW -- FIFA said it was looking into reports of alleged anti-gay chants by Mexico fans during their country's 1-0 World Cup win against Germany on Sunday at Moscow's Luzhniki stadium.
Football's global governing body said it was "collecting the different match reports and potential evidence in regards to the matter, including the one from the anti-discrimination match observer who was present at the game as part of FIFA's anti-discrimination monitoring system."
FIFA added that it could not comment further until it had evaluated all the information.
Mexico fans have long shouted an insult at opposing goalkeeper taking goal kicks that gay rights groups argue is anti-gay.
The country has been fined several times during World Cup qualifying play over the slurs.
Mexico's football federation (FMF) has in the past appealed to fans to refrain from using the chant.
