It seems obvious to me that he is unlikely to decide to move to Saudi Arabia, given that it was his decision to leave the club, which means that the decision to move belongs to him and the club should not interfere with it, so Napoli's agreement with a Saudi Arabian club makes no sense. The English Premier League is where he can fully realise himself and improve his skills, among all possible clubs, Chelsea looks the most suitable for him
For a hot blooded young player like Victor osinimi, it is likely that his football career will build more on the European football league side much more than it will in the Saudi Arabia league, so the young player knows what is best for his football career at this moment in time and that is why he taken the decision to go to club that could help his career more, although Saudi Arabia league is a center of attraction right now, but it still not the favourite of younger footballers.
It was very easy for Christiano Ronaldo to move to the Saudi club's side because he was already at the end of his football career and having long years of European experience.
In fact, only the Saudi team can bring in Osimhen because we can all see how the drama that happened with Napoli and Chelsea regarding the Osimhen transfer agreement, but if there is no big money request from Napoli, maybe there are several big European team that can get him this summer.
Main problem is related to the fee requested by Napoli to reach transfer agreement and the amount requested has been reported to have decreased slightly but that amount is still not something that can be easily issued by several big European team.
It is clear that Chelsea will not be able to bring in Osimhen and the only way is to re-negotiate the agreement with Al Ahli and can become one of the best players here in the future.
Moreover, Osimhen can get quite lot of money and on the other hand he can still develop his career here considering that the SPL also has several strong teams with many great European players.
