Tottenham boss Andre Villas-Boas has urged UEFA to act after Emmanuel Adebayor and Kyle Naughton were targeted by racist chanting at San Siro during Spurs' 4-1 defeat to Inter.
An extra-time goal from the Togo strike ensured the north London club progressed to the Europa League quarterfinals on away goals, yet the team's overall success has been overshadowed by the incident.
Following the full time whistle, Adebayor refused to speak to reporters, and now his Portuguese manager has called on European football's governing body to punish the supporters responsible.
"Chants were very, very easy to hear," Villas-Boas said, speaking after the game. "It's difficult for Inter, we have seen it before. It doesn't mar the game but it is something to be avoided."
Lazio was fined 120,000 pounds by UEFA after its fans racially abused Spurs players in their meeting at the Stadio Olimpico in the Europa League group stage back in November, while it was also punished for similar behavior in the meeting at White Hart Lane earlier in the season.
