Inter Milan president Moratti defends his players after Napoli defeat
Joel Obi is now the seventh Nerazzurri player sent off in 16 of their games officiated by Gianluca Rocchi.
"The players certainly did not disappoint me, as they played well and gave me the certainty we'll see a great Inter this season," said Moratti.
"What did disappoint me was Rocchi's refereeing, which was so bad that he even got pig-headed in sticking by this attitude for the whole 90 minutes.
"Just think, he didn't even have the courage to send off Claudio Ranieri when he was on the field, but rather sent an emissary to tell him at half-time.
"A character like this does huge damage to the club. He was just awful. I hope something changes."
