Kevin-Prince Boateng is free to rejoin Milan in January after he and Schalke mutually agreed to terminate his contract.
Schalke has agreed to terminate the contract of attacking midfielder Kevin-Prince Boateng.
Boateng - who moved to Schalke from AC Milan in August 2013 - is expected to rejoin Milan and has already been training and playing in friendlies with the Serie A outfit for over two months.
The Ghana international was suspended by Schalke following May's 2-0 defeat at Cologne, with the club blaming a "lack of mutual trust" and informing Boateng he could find a new club.
