The 27-year-old striker, who was poised to join Corinthians this summer before the deal fell through, has been linked with a move to the Serie A side.
Despite speculation, Moratti has revealed that the Argentinian will not replace the former Barcelona frontman.
"Will Tevez be the replacement? I don't think we will get him,” Moratti told La Gazzetta Dello Sport.
"Forlan? Lavezzi? These are the names on which we are working. We are watching, exploring, we'll see.”
