Became the target of racist insults
Even though Man United eventually won the game, fans were still not pleased with the disallowed goal. Many had blamed Son for it.
After the match, Son, who is from South Korea, became the target of racist insults online, some of which can be found in the comments section on his most recent Instagram post.
Spurs has since come out with a statement on its social media pages regarding the "abhorrent" online racial abuse.
Spurs added that it has reported the issue to the social media platforms and will undertake a full review alongside the Premier League to determine the most effective action moving forward.
