Tottenham Hotspur's South Korean forward Son Heung-Min has been subjected to racist abuse in a video shared on Twitter.

In the 21-second clip, Son is asked if he 'does DVDs', before being sworn at by a man, off camera, who identifies himself as a West Ham fan.

The reference to selling DVDs is widely known to be a racist term when aimed at Asian footballers.

A club spokesperson for Tottenham said: 'Racist behaviour is completely unacceptable and we hope that the individual is identified to the authorities and the necessary action taken.'

A West Ham United spokesperson said: 'West Ham United have a zero-tolerance approach to any form of discrimination and unreservedly condemn the actions of the individual in this video.

'Anyone behaving in this manner is not representative of our club and its values, and anybody who witnesses discrimination or abuse such as this at West Ham are urged to contact us in confidence at supporterservices@westhamunited.co.uk'.

The video sees Son being filmed as he signs a autograph for a fan out the window of his sports car, before a man - not captured in the clip - starts shouting at the player.

The abuse echoes that which Son received from Millwall fans in their FA Cup quarter final

He asks the winger if he 'can you get us a copy of the new Planet of the Apes film'. When Son asks what he means, the man yells: 'You do DVDs, you do DVDs'.

Realising what is happening, Son winds up his window, but not before the abuser shouts 'Yeah, West Ham you wanker' at the footballer.

The clip was widely shared on Twitter, with user George Bunce - who posted the video but was not the original filmer of the clip - writing 'Just your typical West Ham fan racially abusing Heung Min Son... #Scum'.

The abuse echoes that which Son received from Millwall fans at White Hart Lane in the FA Cup quarter final last season.

Son answered the racism by scoring a hat-trick as Spurs ran out 6-0 winners over their London rivals.
