Milan have won four of their eight Serie A games in the current campaign, and Inzaghi believes that his side's progress is being well received by Berlusconi, who appointed Inzaghi after sacking Clarence Seedorf earlier this year.
"I spoke to Berlusconi earlier on the phone," the Rossoneri boss told reporters. "We always talk and there are always discussions between us two.
"He tells us about what he wants and puts across his views. He is happy with me and with the team. He always gives us lots of advice that proves to be right.
"I know he is happy about our attacking style of football. He prefers a centre-forward in the box, but we have showed that we can also play in another way - it went well against Lazio and Parma, but not as well against Fiorentina."
Milan meet Cagliari in Serie A on Wednesday night.
