AC Milan forward Rafael Leao has been ordered to pay former club Sporting Lisbon €16.5million (£13.8m), according to reports in his native Portugal.
The 22-year-old is said to have lost an appeal over a contract dispute dating back to June 2018.
Leao decided to terminate his deal with Sporting after roughly 50 of the club's fans, some of whom were armed, broke into the training ground and attacked their own players.
