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.
