Torino boss Sinisa Mihajlovic was angry after their draw with Atalanta yesterday.
Iago Falque's opener for the Granata was cancelled out when debutant Joe Hart's error from a corner allowed Andrea Masiello to score. Franck Kessie's late penalty then completed Atalanta's comeback.
“I'm not going to speak about the referee, but if I get angry there is a reason," Mihajlovic told reporters.
“It's absurd that in two years I have been sent off four times for little things like kicking a bottle and then they don't watch what is going on on the pitch!
“I am not convinced by the penalty either, it punishes us too much. De Silvestri is on the floor, turned away from the ball and does not see the opponent."
