The Italian publication reported that Milan's general director Ariedo Braida was impressed by the 22-year-old's performance while featuring for Serbia in the 1-1 draw with France.

The same report suggests that coach Lenoardo is aiming to beef up his squad in January with midfielders.

Kacar, who joined Hertha in 2007, is a regular at the German side and has been producing praiseworthy displays in the Bundesliga for quite a while.

Milan are yet to confirm their interest in the Serbian ace.
