Lazio players, coaches and directors were claiming scandal after a penalty shout for handball was waved off and Ciro Immobile was sent off minutes later for a headbutt in a 3-1 loss to Torino.

The hosts had Immobile sent off for violent conduct on the stroke of half-time, and Torino made the most of their one-man advantage to secure their first away win against Lazio for 24 years.

The visitors scored three times in 19 second-half minutes to leave Lazio reflecting ruefully on Immobile's red card, which was awarded by referee Piero Giacomelli after the former Borussia Dortmund forward appeared to move his head towards Torino defender Nicolas Burdisso.

But the Immobile incident, which came after video review and the alleged missed call for handball on Torino's Iago Falque, had players calling foul during and after the match.

"Maybe people don't like Lazio in the top four," midfielder Luis Alberto told Mediaset Premium at half-time. "It's incredible, that was a clear penalty.

"You can't play football like this and in too many games this has happened to us. Maybe people don't like Lazio being in the top four. Now we want to win even more! We're coming out for the second half and will definitely win now."

Following the match, Lazio boss Simone Inzaghi said the match was decided by the referee in the second half of a match that he believes his team were cheated of victory.
