Javier Pastore hit the winner for the Rosanero, but Rossi upset with several penalty shouts being turned down.
"People always have to say 'probable' penalty when talking about it, but again this foul was as big as a house," snapped the Coach.
"There has been an odd sort of effect on the referees, so when in doubt, they won't give it to us.
"Many tell me Palermo do not have the charisma to make themselves respected, but I want to think we are simply unlucky, as the rules are equal for everyone.
"The situation has become absurd. We are not Barcelona, so we are always forced to give it our all.
"I have to praise my lads for emerging with the three points, as these games are always tough. Cesare Bovo's free kick gave us a very important win."
