Milan are trying to put together a transfer package to lure Real Madrid stopper Sergio Ramos, according to Il Corriere dello Sport.
The report claims directors at Milanello have made finding a right back and a left back their priorities, and work is already underway.
Ramos, 24, is said to have refused offers in relation to a new deal at the Bernabeu - a signal he wants to explore football away from the Spanish capital.
The Rossoneri are observing the situation with Ramos, but should that fail, they will turn to Palermo's Mattia Cassani and Roma defender Marco Cassetti as alternatives.
Lyon's Aly Cissokho continues to be linked with a left-sided role at San Siro. He was previously close to joining them two years ago.
Ariedo Braida was in Lyon for their Champions League clash against Real Madrid on Wednesday night.
He was seen dining with French chiefs in an attempt to lay the ground for Cissokho.
On Thursday, Cissokho's agent described a move as being "possible".
