AC Milan are monitoring Artur Boruc's situation at Celtic.
The Poland international has threatened to buyout the remaining two years of his existing contract at the end of this season - which has alerted Milan to the prospect of landing the shot-stopper for a knockdown fee in the summer.
Milan chiefs see Boruc, 27, as an ideal replacement for 34 year-old Dida and are prepared to compete for his signature should the Pole carry through with his contract threat.
