Rossoneri officials were apparently at Chelsea this weekend to lodge their interest in the Spaniard and enquire about his availability in January
AC Milan began talks with Chelsea on Saturday to sign Cesc Fabregas in January, reports Tuttosport.
The midfielder does not appear to be part of Antonio Conte's plans at Stamford Bridge and the Rossoneri are ready to swoop.
Milan are in the process of being bought over by a wealthy Chinese conglomerate that could fund an operation.
And directors Marco Fassone and Massimiliano Mirabelli were reportedly at Chelsea to discuss Fabregas' situation, with the club considering him a potential replacement for the injured Riccardo Montolivo.
