European football's governing body UEFA could take action after claims that racist chants were made at Thursday night's match between Tottenham and Lazio at White Hart Lane.
Three Spurs players were apparently targeted by some of the Italian club's supporters.
It has also emerged that a Chelsea player has also been racially abused. Chelsea manager Roberto Di Matteo and Arsenal manager Arsene Wenger have said racism in football must stop.
