The fallout from Sunday's ill-tempered Milan derby continued as AC Milan captain Massimo Ambrosini was banned for one game and club vice-president Adriano Galliani called referee Paolo Valeri "technically inadequate".
Corriere dello Sport reported that Ambrosini, an unused substitute in the 1-0 defeat, had argued with the referee in the tunnel at half-time before storming on to the pitch at full-time to continue his protests.
As a result of his actions, and fans displaying a banner insulting former Milan player Antonio Cassano, now at Inter, the Rossoneri were fined €8,000 by the Italian FA and Ambrosini handed the ban.
Galliani followed the lead of Milan coach Massimiliano Allegri in hitting out at the referee, saying: "You all saw what happened. The referee was worth four out of ten on a report card - and if all the newspapers have given a four to Valeri then there must be a reason for it.
"I've been told by our lawyers that if I say his performance was technically inadequate then I don't risk being punished.
"His performance in the whole game was strange - our problems were compounded by the problems of the referee, and that disappoints me."
Speaking after Sunday's match, the Inter president Massimo Moratti compared his coach Andrea Stramaccioni to Jose Mourinho after he steered Inter to victory despite the first-half sending off of Yuto Nagatomo.
"I chose Stramaccioni for his technical abilities but also his intelligence. In my view, the thing that makes him most similar to Mourinho is his dedication to work," Moratti said.
"Like Mou, Stramaccioni is also a great coach. The defence did very well, and the credit goes to the coach for making the right decisions."
Stramaccioni laughed off the complaints from Allegri, saying: "We were the ones who had someone sent off."
