Thes South Korea skipper was at the centre of a controversial incident in the first half, which saw Manchester United’s goal chalked off after Scott McTominay was adjudged to have fouled Son in the build-up.

Son then scored the opening goal of the game three minutes later.

Manchester United boss Ole Gunnar Solskjaer spoke out after the game, criticising Son and saying that “the game is gone” after the decision to disallow the goal.

“If that was my son and he stays down and he needs his mates to help him up, he doesn’t get food because that’s embarrassing,” Solskjaer said after the game.

“The game’s absolutely gone.”

Solskjaer said that the referee had been conned by Son

“If that’s a clear and obvious error, it’s an obvious error he had to look at it. It was a perfectly good goal. They are conned [by Son]. We weren’t conned, the referee was.

“Unfortunately the referee decided we are not playing football or VAR decided probably. I’m absolutely shocked if that is a foul.”

Spurs boss Jose Mourinho did not mince his words in response to Solskjaer, the man who replaced him in charge of the Old Trafford side.

“First of all, let me tell you something. I’m very, very surprised that after the comments that Ole made on Sonny, you don’t ask me about it,” Mourinho said.

“Because - and I told Ole already this because I met him just a few minutes ago - if it’s me, telling that player A, B or C from another club, if it was my son I wouldn’t give him dinner tonight, what would be the reaction of that?

“It’s very, very sad. I think it’s really sad that you don’t ask me about that. It’s sad you don’t have the moral honesty to treat me the same way as you treat others.

“In relation to that, I just want to say that Sonny is very lucky that his father is a better person than Ole. I am a father. I think as a father you have always to feed your kids. Doesn’t matter what they do. If you have to steal to feed your kids, you steal.

“I’m very, very disappointed. As we say in Portugal, bread is bread and cheese is cheese. I told Ole already what I think about his comments and I’m very disappointed that in five, six, seven questions you ignore the dimensions of that comment.”

The 28-year-old was targeted by racists online, with comments coming in response to a tweet from the official Spurs account and on his personal Instagram account.

Footballers have increasingly become the target of racial abuse online, with English Championship side Swansea City leading a social media boycott that has been followed by Scottish champions Rangers.

Former Arsenal player Thierry Henry has also stepped back from social media because of racism in a move that several current players, including Son’s Spurs teammate Gareth Bale. have said they would consider.

Twitter and Facebook, who also own Instagram, have been criticised for allowing racist abuse on their platforms.
