Victor Osimhen can leave Napoli permanently for €90m in the January transfer window, according to RAI Sport.
Osimhen joined Galatasaray on a season-long loan deal earlier this month.
The striker reportedly extended his Napoli contract until June 2027 before leaving the club on a temporary transfer, and his release clause was lowered to €75m from €130m.
According to RAI Sport, there is another clause which allows the Nigeria international leave Napoli during the winter transfer window.
The clause is however not valid for Serie A clubs.
Serie A giants Juventus have been recently linked with the 25-year-old.
Osimhen has registered two goals and two assists in three league appearances for Galatasaray.
