Tottenham are investigating a report of racist abuse towards South Korean forward Son Heung-min during the club's 1-0 defeat by Manchester United
Spurs, whose manager Mauricio Pochettino recently said he wanted to 'kill racism', are working with a season ticket holder who tweeted about the abuse mid-game.
Among a series of tweets detailing what happened, supporter James Dickens wrote: 'I've not experienced racism at football for about 15 years. But today at @SpursOfficial was hideous.
I've not experienced racism at football for about 15 years. But today at @SpursOfficial
was hideous. Reported to stewards, confronted him myself and was called a c*nt. While I was standing next to my son. Hideous.

'Reported to stewards, confronted him myself and was called a c***. While I was standing next to my son. Hideous.'
In a later tweet, he said Tottenham had contacted him and were looking into the claim, which occurred during Sunday evening's game at Wembley Stadium.
With racist abuse at football heavily in the news over the past months, Spurs boss Pochettino recently described his thoughts on a fan throwing a banana at Arsenal forward Pierre-Emerick Aubameyang during the north London derby.
'Our fans, Arsenal fans, Chelsea fans, [fans] around the world, we need to celebrate for us,' Pochettino said at the time. 'I don't care if it is Arsenal fans, Argentina fans, Tottenham fans, Espanyol or Barcelona fans - I am against this type of situation.
'For me, it [racism] is the worst thing in the world and that is why I am completely against this behaviour. I don't want to be populist. I don't care whether it is our fans or other fans. I want to kill racism. Our responsibility is to behave like this.'
A Tottenham game was also in the news last week when three Chelsea supporters were investigated for racially-aggravated public order offences during the Carabao Cup semi-final first leg match.
In Sunday's match, Marcus Rashford scored the only goal as Manchester United ran out 1-0 winners to continue their fine form under new boss Ole Gunnar Solskjaer.
Spurs striker Son headed straight to the airport after the game, and was pictured arriving in Dubai early on Monday as he begins his Asian Cup campaign with South Korea.
