Saudi? hmm I think it is not wise to go there, but that is where the money is for him to have a career, it's just not necessarily long-term because the Saudi league has not built its reputation too far, while going to Galatasaray is not a bad thing if we talk about reputation and it is also good enough to develop yourself, it's just that it can't be compared to the popularity of the league, the Italian league is much more popular.
Osimhen does need to improve his quality again. The injury made him get less attention and his performance became unstable and like before when Napoli dominated one season of the Serie A league.
If you look at the salary request requested by Osimhen to several teams, it is not unwise to go there because only the Saudi Arabian league is willing to pay him a big salary. Although for a career it is not the right step to decide to play in that league because Osimhen is still young enough to develop in Europe. But again he made a slightly more wrong decision moving to Galatasaray as a loan player and I think the league there only has a slightly better popularity rating compared to the Saudi Arabian League. Osimhen needs to improve his game if he wants to be a player targeted by other clubs next season and I have little doubt that he will be targeted by many clubs next season.
It's too early for him to go to the Saudi Pro League, because he's still quite young and it would be a shame if he spent time playing in a less competitive league. While in Europe he can continue to develop his abilities very well and in the future he can become a player who will be more valuable than he is now. In my opinion he should be able to lower his ego regarding the salary he wants, because not all teams will be willing to pay him, especially when they also have to pay a high price from Napoli who still owns Osimhen. In my opinion, his move to Galatasaray was only to get playing minutes, because his chances of getting enough playing minutes with Napoli have been slightly closed after Conte said he didn't really need Osimhen in his squad.
