Lazio striker Paolo Di Canio could find himself in trouble with the Italian football authorities once again after giving an alleged fascist salute in Sunday's Serie A match away to Livorno.

According to Italian news agency ANSA, Di Canio made the gesture to the visiting Lazio supporters while he was being substituted.

Games between Livorno and Lazio are always tense because of the political leaning of the clubs' supporters. Livorno have always had a strong left-wing following, while Lazio supporters have links to the far right.

ANSA said Livorno fans waved communist flags with the hammer and sickle emblem, while Celtic crosses (a popular symbol for the neo nazis especially as the swastika is banned) were spotted in the Lazio enclosure.

It is not the first time Di Canio's politics have landed him in hot water. In March he was fined 10,000 euros for giving a fascist-style salute at the end of the Rome derby two months earlier.

Di Canio denied any political significance but the Italian football league's disciplinary commission ruled his gesture had "unequivocally recalled a precise political ideology which could have provoked a violent reaction from fans".
