Inter risk disciplinary proceedings after their fans were accused of racist behaviour during the Europa League last 16 clash at home to Tottenham Hotspur.

A statement from UEFA said the Serie A club were under investigation for “racist behaviour of supporters, insufficient organisation and the throwing of missiles and/or fireworks”.

Tottenham striker Emmanuel Adebayor, who scored his side’s away goal in a 4-1 defeat in Thursday’s second leg, was allegedly subjected to monkey chants and plastic bananas were waved in one section of the half-empty San Siro.

Tottenham manager Andre Villas-Boas, whose team went through on away goals after the 4-4 aggregate score, told reporters after the game that it was “very easy” to hear the chanting and said he hoped UEFA would act.

Last month, Inter were fined €50,000 by the Italian league after fans racially abused their former player Mario Balotelli in a derby with Milan.

Meanwhile Lazio, who have a long-standing right wing element among their support, were ordered by UEFA to play two European matches behind closed doors after racism by their fans in Europa League matches against Tottenham, Maribor and Borussia Moenchengladbach.
