Parma boss Roberto Donadoni was left frustrated by their Coppa Italia defeat to Juventus.
Alvaro Morata struck an 89th minute winner for Juve.
"We put in a great performance and I am disappointed, as we lost at the last minute to an offside goal," Donadoni told Rai Sport.
"On Sunday we were disadvantaged by a refereeing error too. These are two undeserved defeats and I am sorry for the lads, who are suffering with the current situation and losing through no fault of their own hurts even more."
