Since joining the Rossoneri, the Nigerian has struggled to replicate the form that made him a household name at the Yellow Submarines during his five-year stay at Estadio de la Cerámica.
Chukwueze has made 41 appearances for Milan, scoring three goals and as many assists since arriving at San Siro.
The 25-year-old has struggled to break into the starting XI this season and has been sparingly used as a substitute.
Recently, Milan manager Paulo Fonseca confirmed that Chukwueze had no space on his team, urging the Nigerian to make a move elsewhere.
Not short of suitors, the winger was immediately linked with moves to La Liga giants Atletico Madrid and Premier League duo West Ham and Aston Villa.
