The Giuseppe Meazza side had a questionable penalty awarded against it in Sunday's encounter, while referee Andrea Gervasoni waved play on after Inter felt it deserved a spot kick , much to the dismay of Moratti.
He stated on Monday that he felt the referee's decisions were 'not in good faith' and he has now suggested that referees are deliberately hindering his team when he was asked to explain his comments.
"I really don't think I need to explain anything better. You only have to look at the way this season has gone, especially regarding us," Moratti told reporters. "When people want to hit you, they do it anyway."
He added, "When there's a doubt, the penalty on Rocchi doesn't get given. When there's nothing to doubt – because there was nothing there – the penalty against us does get given. We haven't had a penalty for 21 games."
As a result of its latest defeat, Inter has now dropped to sixth spot in the Serie A table.
