UEFA have confirmed they have opened disciplinary proceedings against Lazio for the alleged racist behaviour of some of their fans during Thursday night's Europa League clash against Tottenham.
Aaron Lennon, Jermain Defoe and Andros Townsend all appeared to be the subject of monkey chants from the away end during Spurs' 0-0 stalemate against the Italian side at White Hart Lane.
After receiving reports from referee Ovidiu Alin Hategan and match delegate Adonis Procopiou, European football's governing body charged the Rome-based club with improper conduct.
A statement read: "UEFA has opened disciplinary proceedings against S.S. Lazio for the improper conduct of the club's supporters (racist behaviour) during the UEFA Europa League group stage match on Thursday 20 September between Tottenham Hotspur FC and the Italian side."
UEFA's Control and Disciplinary Body will hear the case on October 18.
