The Rossoneri lost 1-0 despite Yuto Nagatomoâ€™s red card after 48 minutes, but they were furious at several controversial decisions.
Riccardo Montolivoâ€™s goal was disallowed for an Urby Emanuelson coming together with Samir Handanovic, while Walter Samuel appeared to block off Robinho in the box.
â€śSeeing as I never talk about referees, Iâ€™m afraid I have to now. The referee affected the game,â€ť snapped Allegri on Sky Sport Italia.
â€śIt was a technical error, as he blew the whistle for half-time 12 seconds early. There was a last man foul on Emanuelson which was given against him. There was maybe a penalty on Robinho, the Nagatomo red card was obvious as he couldnâ€™t not give him another yellow for that.
â€śThis is not an alibi and perhaps today the referee was unlucky, but the incidents were really obvious.
â€śI have no idea what the referee whistled for on the Montolivo goal. Letâ€™s just say he was unlucky on the decisive incidents, as the goal wouldâ€™ve been crucial, there was a penalty and Samuel was last man too.
â€śItâ€™s not as if the referee did us a favour with Nagatomoâ€™s red card, as he obviously stuck his arm out for an intentional handling offence.
â€śItâ€™s a shame we are running into some decisions that go against us, but we canâ€™t do anything about that. Maybe the referees are on as bad form as we are."
