Simic, 31, is yet to make an appearance for the Rossoneri this season and has lost patience with boss Carlo Ancelotti.

"I am shocked by my current situation," said Simic. "Last season I played 35 games and this campaign I haven't made one appearance.

"I don't think I have anything to prove. I have made 100 appearances for my national team. The fact that I'm not playing is not good for me and I've decided to leave Milan in January."

Simic joined the European champions from city rivals Inter Milan in the summer of 2002 and is Croatia's most capped player.
