Andre Villas-Boas is happy to leave UEFA in charge of any potential sanction against Lazio after the Italian club's supporters allegedly aimed monkey chants at three Tottenham players during last night's Europa League stalemate between the two sides.

Jermain Defoe, Aaron Lennon and Andros Townsend all appeared to be the subject of racist taunts from the visiting fans during the 0-0 draw at White Hart Lane.

UEFA, whose president Michel Platini was at the game, are aware of reports of monkey chanting and may decide today to open disciplinary proceedings against the Italian giants.

Villas-Boas did not hear the chants and is therefore happy to leave European football's governing body to decide on whether any action is appropriate.

"I think (UEFA will act if the accusations are proven)," Villas-Boas said in his post-match press conference.

"UEFA is very active on this kind of situation and our overall objective is to kick racism out of football.

"I can't point the finger at anyone in any way shape or form tonight because I didn't hear anything. It's for the authorities to follow up in any kind of investigation."
