Tottenham are to “determine the most effective action moving forward” after Son Heung-min suffered “abhorrent” racist abuse on social media.

The South Korea forward was abused following Sunday’s 3-1 Premier League home defeat by Manchester United.

Team-mate Davinson Sanchez received racist messages on social media after a 2-2 draw at Newcastle on April 4.

Son, who scored for Tottenham in Sunday’s defeat, was involved in an incident in which Manchester United had a goal disallowed after he was caught in the face by Scott McTominay.

Tottenham said last week they wanted “social media platforms to take action” after defender Sanchez was subjected to racist abuse.

On Friday, a number of Premier League managers called for a football-wide boycott of social media, in response to the increasing frequency of racist abuse sent to footballers.

Scottish champions Rangers, plus Championship clubs Swansea and Birmingham, are boycotting social media for a week to combat abuse.

Liverpool also said racist abuse on social media “cannot be allowed to continue” after Trent Alexander-Arnold, Naby Keita and Sadio Mane were targeted.
