Tottenham boss Andre Villas-Boas wants UEFA to take action against Lazio over alleged racist chants from their home fans during last night's Europa League 0-0 draw.
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."
