The France international’s contract at San Siro has expired few days ago, and he was offered a new two-year deal at the club.
However, the player was not satisfied with the terms of the new contract and has decided to leave the Rossoneri after five years.
“With regards to what he has done at the club, Mathieu wanted a longer contract,” agent Alexandra Missirli explained to L’Equipe.
Flamini appears to have set his sights on leaving the Italian giants and he will have no shortage of offers after becoming a free agent.
Inter and Napoli are believed to be keen on the experienced midfielder, while a return to English Premier League is also an option.
Flamini joined Milan in the summer of 2008 on a free transfer from Arsenal and has since amassed 96 Serie A appearances, scoring 7 goals.
The player’s career at San Siro was plagued with injuries, but he did eventually manage to nail down a regular starting berth.
