The director of the Serie A leaders believes that the referee of Sunday's match lacks experience and did not have the courage to award his side a clear penalty
The Bianconeri had a penalty claim waved away by referee Sebastiano Peruzzo in dying stages of the match as Giorgio Chiellini's cross struck the arm of Simono Vergassola.
"I would like to speak with [referee designator Stefano] Braschi, but since that is not possible, I will discuss the state of refeereing through the media," Marotta told Sky Sport Italia.
"Today, we were clearly damaged as we were not awarded a clear penalty. Even though we are topping the table and we have the best attack, we are last when it comes to the number of penalties, with just one spot-kick received all season.
"All we are asking for is respect for our team. It is only natural that the Serie A leaders should be assigned referees with international experience. But Peruzzo was afraid to award us a penalty.
"If we see the penalty which Fiorentina received today, it was identical to the one that we were not given. We need more consistency in the referees' decisions."
Juventus remain one point clear at the top of the Serie A table and still have one game in hand.
