Tottenham Hotspur have condemned alleged racist abuse directed towards Son Heung-min during their home win against Crystal Palace.
Posts on social media appear to show a man in the away end making a gesture at the South Korea forward on Saturday.
"Discrimination of any kind is abhorrent and has no place in society, our game and at our club," said Spurs.
Palace added: "Evidence has been shared with the police, and when he is identified, he will face a club ban."
The Eagles, who were beaten 1-0 at Spurs in the Premier League, said they were "aware of a video circulating online (as well as reports made directly to us) regarding an individual in the away end at Spurs, appearing to make racist gestures towards Son Heung-min".
