Paris St-Germain are investigating allegations the club racially profiled young players in order to limit their number of black academy players.
French website Mediapart made the claims and published leaked documents.
PSG have said that between 2013 and 2018, their scouting department filled out evaluation forms on some young players, including stating ethnicity.
They are investigating “to understand how such practices could exist and decide what measures must be taken”.
PSG general manager Jean Claude Blanc told BBC Radio 5 live he was “shocked” and “felt betrayed”.
