Chelsea are investigating a video midfielder Enzo Fernandez posted on social media which the French Football Federation (FFF) allege shows them singing a racist song.

Fernandez posted on Instagram after Argentina's Copa America victory over Colombia, showing him and his teammates chanting about the France national team.

Wesley Fofana, Fernandez's Chelsea teammate, has reposted the video on social media with the caption: "Football in 2024: uninhibited racism".

The FFF has alleged that the song sung by Argentina's national team is "racist and discriminatory".

In a statement they said: "The president of the French Football Federation, Philippe Diallo, condemns in the strongest terms the unacceptable racist and discriminatory remarks which were made against the players of the French team in the context of a song sung by players and supporters of the Argentina team after its victory in the Copa America and broadcast in a video on social media.

"Faced with the seriousness of these shocking remarks, contrary to the values of sport and human rights, the president of the FFF decided to directly challenge his Argentinian counterpart and FIFA, and to file a legal complaint for insulting remarks of a racist and discriminatory nature."

Argentina beat France in a penalty shoot-out in the 2022 World Cup final and during the match some fans were heard to sing discriminatory songs, Sky Sports News reported.
