UEFA has punished the Italian side with a 45,000 euro fine after fans waved inflatable bananas at Emmanuel Adebayor and his teammates during their Europa League match in March.
The Togolese scored during extra-time of the second leg of the tie to put Spurs through on away goals, but he and his teammates were the victims of abuse by Nerazzurri fans who waved inflatable bananas at them.
The Italian club had already been fined by Serie A authorities after former Manchester City striker Mario Balotelli was the subject of racism during its derby clash with AC Milan.
Tottenham boss Andre Villas-Boas publicly asked UEFA to hand out a more stringent punishment in the wake of the incident involving Adebayor during his side's clash at the San Siro.
Earlier in the season, fellow Italians Lazio were also fined for racist chanting from supporters in their Group J encounter with Tottenham at White Hart Lane, while they were again punished for similar behavior in November's return game in Rome.
