To leave the European stage, it seems that Osimhen is not ready yet, he has said several times that he still wants to play in Europe compared to the Saudi Arabian league. But we also don't know what will happen in the future because minds can change in every transfer market. Of course it would be very good for Osimhen if he joined the Saudi Arabian league because he would be offered a higher salary compared to the salary he currently earns.
Victor Osimhen is still been paid very well at Galatasaray so maybe he mightn't want to leave yet and if he decides to leave, it mightn't be in January. He isn't also that hungry for money or he would had forced his move to the Saudi pro league when he had the chance. He's a player that wants to achieve so much from Europe that's why he still wants to play in Europe and not the Saudi pro league. He wants to be among some of the great players that have achieved success playing football and winning lots of trophies in Europe, he has always said that in his interview so we shouldn't think he'll ignore other clubs calling him to play in Europe for the Saudi pro league.
