The Granata blew a two goal lead before Alex Berenguer's goal gave them a crucial three points.
“I'm tired of losing points, I can say that now we've won," Mazzarri fumed on Sky Italia.
“The referees are affecting the results and they were trying again today because it was a foul on Sirigu for 2-1.
“Today Sirigu was catching the ball and was prevented from playing it. It's not the first time, it's a continuation.
“When we're constantly trampled on I get tired, it deserves more attention. Today we won, even in a match that was up for discussion.
“Is there a campaign against Torino? I don't know. I see ugly, strange attitudes. A fourth official that cannot speak."
