FIFA say it has issued Football Federation Australia with a warning after four Socceroos fans were allegedly caught singing a homophobic chant at the Australia-France World Cup match in Russia.

However, despite FIFA's statement to Fairfax Media confirming the caution, FFA said it has received no notification from FIFA about the warning.

FIFA's statement read: "We can confirm that FIFA’s Disciplinary Committee issued a warning to the Australian Football Federation related to a very small group of fans (4) singing a homophobic chant during the 2018 FIFA World Cup match between France and Australia.

"As usual, the decision was passed after having analysed the respective evidences at hand and after having taken into account all factors surrounding the infringement, including the fact that the incident was triggered by a very small group of fans."
