Tottenham's Heung-Min Son was allegedly the subject of racist chants during Sunday's match against Millwall

Tottenham will hand over CCTV footage to help catch those who directed racial abuse at Heung-Min Son during Sunday's FA Cup tie against Millwall at White Hart Lane.

A section of the away support sang derogatory chants about the South Korea international - and the Football Association are investigating allegations against both sets of fans.

In a club statement, Tottenham said: "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."

Two men have been charged with public order offences.

FA chief executive Martin Glenn has expressed his disappointment with the chants but was keen to stress how rare incidents such as these have become in English football.

Glenn told Sky Sports: "I felt disappointed and the reason why I felt disappointed is because you don't hear it much in football or see it much in football anymore.

"I think football has cleaned itself up. Football in England is far more intolerant of any kind of phobia whether it be racism or homophobia then just about any other country in the world and we don't give ourselves credit for that.

"The fact that there was chanting, the fact that it was picked up and the fact that everyone is in uproar about it, starting with Millwall, shows how strong the values are in English football."

Lions manager Neil Harris said after the game he was expecting the authorities to look into chanting from the away end but both Harris and Mauricio Pochettino denied hearing anything untoward during Spurs' 6-0 quarter-final win, in which Son scored a hat-trick.

"What I will say is me personally - and 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 to 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 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."
