Claudio Marchisio is Milan's alternative to Marek Hamsik and would cost just under €20m to prise from Juventus.
The Rossoneri have declared numerous times they want reinforcements for the midfield, particularly down the left side.
The primary target was Hamsik, but Napoli have slapped a €100m asking price on him and pointed out Inter would have first pick.
According to Tuttosport today, Milan are turning their attention to Juventus starlet Marchisio.
A product of the Juve youth academy, he is a regular in the Italy starting XI and does not seem to fit within new Coach Antonio Conte's tactics.
Marchisio only recently signed a contract extension, but before then had been heavily linked with Inter.
