Moratti believes Conte is too clever to consider such a move.
He told Gazzetta dello Sport: "He is a great manager, the only difference with [Luciano] Spalletti is that Spalletti has yet to win a Serie A title, Conte has already won league titles in Italy and in England.
"If he'd joined Inter and failed it would have been Inter's fault.
"A move to AC Milan? No, I don't think so, he is a smart guy."
Milan currently sit in eighth place in the Serie A standings - 18 points behind fierce city rivals Inter.
