Andre Villas-Boas has urged UEFA to take action against Lazio if their fans are found guilty of chanting anti-Semitic songs at Tottenham during Thursday night's Europa League draw at the Stadio Olimpico.

The home supporters chanted "Juden Tottenham" during the first half of the goalless draw, which came the day after fans of the London club were attacked in a vicious scuffle in a city centre pub. UEFA had fined Lazio £32,500 for their fans monkey chanting at three Spurs players during the reverse fixture in September.

And Villas-Boas hopes the organisation move swiftly to establish the facts. "It will take another investigation," the Tottenham manager told a press conference. "It happened last time and it was acted upon quickly by UEFA. We will have to wait and see if there is anything to act upon. If there is UEFA have to act."
