Milan are thought to be offering €5m for Atletico Madrid full-back Guilherme Siqueira.
The Rossoneri need reinforcements after Mattia De Sciglio and Cristian Zapata were ruled out for four to six weeks by injury.
According to Sky Sport Italia, the initial proposal for Siqueira will be worth €5m and the fax will formally be sent on Monday.
However, this is only a starting point for negotiations, as Atleti paid €10m for the 28-year-old Brazilian in June.
