Tottenham will provide video footage to the Football Association in a bid to help identify any fans guilty of racist chanting during Sunday's FA Cup quarter-final against Millwall.

Millwall supporters were heard chanting "DVD" and "You're selling three for a fiver" at Spurs' South Korean striker Son Heung-min, thought to be in reference to the racist stereotype of traders selling bootleg copies of films.

Son responded by scoring a hat-trick in Tottenham's 6-0 victory at White Hart Lane as further goals from Christian Eriksen, Dele Alli and Vincent Janssen sealed progress to the competition's last four.

It is understood the FA has begun investigating the allegations of racist chanting. The governing body will seek evidence from referee Martin Atkinson's match report, as well as observations from the clubs and police.

A Tottenham club spokesman said: "We strongly condemn the use of any racist language.

"We shall be passing on all of our footage to the relevant authorities which can assist with the identification of anyone responsible for such chanting at yesterday's game."

A Millwall statement read: "Millwall have led the way on anti-discrimination initiatives and will continue to do so.

"The club is assisting The FA with their investigation and will make no further comment until that process is complete."

Millwall manager Neil Harris said after the match he had not been aware of the chants but accepted that, if proven, they would represent a blot on his side's excellent run in the competition.

"I didn't hear anything, but the club, we won't condone that," Harris said.

"We came here in the right spirit, to enjoy an FA Cup quarter-final, so if that's proven to have been to the detriment of the competition then I'm sure it will be left to the authorities. We just want people to enjoy the game.

"Of course it's a shame, for both of us - Mauricio (Pochettino) wants to be talking about his team's quality.

"The focus comes away from what we've achieved in the competition. It's wrong in society and it's wrong in football."
