AC Milan representatives have approached the agent of Inter Milan goalkeeper Francesco Toldo this week.
Toldo is off contract in the summer and ready to quit Inter after losing his No1 status to Brazilian Julio Cesar this season.
Milan vice-president Adriano Galliani and transfers chief Ariedo Braida are keen to sign Toldo next month as concerns grow over the form of current No1 keeper Dida.
Milan patron Silvio Berlusconi mentioned their interest in Toldo informally with Inter's Massimo Moratti during Sunday's derby.
