Tottenham Hotspur said they were disgusted by online racist abuse received by Colombia defender Davinson Sanchez after the 2-2 Premier League draw at Newcastle United on Sunday.
"We are disgusted by the racist messages received by Davinson Sanchez today and are calling on social media platforms to take action," the London club said on Twitter.
"We stand with you, @daosanchez26 and all those continuing to suffer abuse online."
Sanchez shared a screenshot of an Instagram account which posted a string of monkey emojis on his page.
He is the latest in a long list of players targeted by online abuse including Manchester United trio Anthony Martial, Axel Tuanzebe and Marcus Rashford plus Chelsea's Reece James.
