Chelsea are investigating a video Enzo Fernandez posted on social media which the French Football Federation alleges is racist.
Fernandez's post on Instagram shows him and his Argentina chanting about the France team after their Copa America victory over Colombia.
Wesley Fofana, his Chelsea team-mate, reposted the video on his X, formerly known as Twitter, with the words: "Football in 2024: uninhibited racism".
The French Football Federation has said it will file a legal complaint alleging "racially offensive and discriminatory remarks" were made by Argentina players following their Copa America victory over Colombia on Sunday night.
In a statement, the FFF - the governing body of French football - said its president Philippe Diallo would challenge FIFA president Gianni Infantino and Argentina Football Association boss Claudio Fabian Tapia to respond to the alleged remarks.
The statement read: "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."
