Italian side Lazio will face disciplinary proceedings after their fans were accused of racist behaviour during the Europa League clash at Tottenham, UEFA said on Friday.
Monkey chants were aimed at three of Tottenham's black players, Jermain Defoe, Aaron Lennon and Andros Townsend during the game at White Hart Lane which ended in a 0-0 draw.
"UEFA has begun disciplinary proceedings against Lazio for 'improper conduct' by the club's supporters during Thursday's Europa League tie against Tottenham," said a UEFA statement.
"The Control and Disciplinary Body will meet on 18 October to discuss the case."
Tottenham boss Andre Villas-Boas had said after the match that UEFA should take action if there was a case to answer.
"UEFA is very active on this kind of situation so and our overall objective is to kick racism out of football," said Villas-Boas.
