The 26-year-old France international was linked with a move away from St. James’ Park in the summer, with Premier League giants such as Arsenal and Liverpool interested in securing his services.
However, a deal never materialised and he stayed put at Newcastle. He also stated recently that he is happy in England and is enjoying playing week-in-week-out with Steve McClaren’s men.
But Newcastle’s poor start to the season is said to have had an effect on the player and it has been suggested that he has asked the club to allow him to leave in January.
And according to Italian broadcaster Sport Mediaset, AC Milan are pondering over securing his services in the winter transfer window.
Sinisa Mihajlovic wants to further strengthen his midfield in January and the 26-year-old France international is one of the first names on his shortlist.
The Rossoneri have made a poor start to the season and are looking to strengthen their squad in the winter transfer window to improve their standing at the end of the campaign.
Sissoko has a contract until 2019 with Newcastle United.
