It is now obvious that Victor Osimhen is really serious about staying and playing in Europe for him to turn down such an offer from Saudi this clearly shows his preference and how much he values staying in Europe and winning European trophies and achieving bigger achievements and acknowledgment in Europe.
European clubs and leagues are the biggest dream of most young players who are still at the prime of their footballing career, so for that we can't entirely blame him for choosing to remain in the European clubs side, he made all the name for himself from there so why the rush to change leagues by optioning to take up offer's from teams like from the Saudi Arabian sides, I don't see much future for Victor in AI Halil in the first place so his decision is a welcome one.
With his talent and quality, Osimhen can still earn a large amount of income when he decides to stay in Europe, therefore rejecting the offer from Al Hilal is indeed a very wise decision. Many top European clubs need a pure striker like Osimhen, Manchester United is one of them, maybe this season everyone will see Osimhen playing in the Premier League.
Napoli will not dare like last season, if they set the price too high which makes it difficult for Osimhen to find a new club, next season they will lose him for free. In my opinion, Osimhen still has plenty of time to move to Saudi, and for the next few seasons, he should stay in Europe. Galatasaray has so far tried to keep him, but financially, they are not strong enough to make it happen.
