Tottenham Hotspur called for social media companies and authorities to "take action" after online racist abuse was directed at Son Heung-min following his goal against West Ham on Sunday. South Korea captain Son emerged from the bench in the second half to net Spurs' second goal in the 2-0 win in the London derby at the Tottenham Hotspur Stadium. "We have been made aware of the utterly reprehensible online racist abuse directed at Son Heung-min during today's match, which has been reported by the club," Tottenham said on the club's official Twitter feed on Sunday night.
