Tottenham have called for social media companies to take action after Son Heung-min was subjected to "utterly reprehensible" racist abuse online.
Tottenham posted on Twitter saying they had reported the abuse towards Son.
"We stand with Sonny and once again call on the social media companies and authorities to take action," they said.
Tottenham added: "We have been made aware of the utterly reprehensible online racist abuse directed at Heung-Min Son during today's match, which has been reported by the club."
Anti-racism group Kick It Out earlier this month demanded "meaningful reforms" after Brentford striker Ivan Toney was subjected to racial abuse on Instagram.
