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.
Osimhen seems to be playing with his own career, he asked for a bigger salary than what he received at Napoli, but when Al-Ahli proposal came with a luxurious offer, he rejected it because he still wanted to play in Europe. Previously Chelsea and PSG wanted to bring him from Napoli, but the deal did not happen due to salary issues. Now he has to accept the consequences of his unprofessional attitude, he has been loaned to Galatasaray after Napoli dropped him from Conte's squad. Although the popularity of the Turkish League is a bit lower than Serie A, EPL, La Liga and Bundesliga, at least he is still playing in the Europa League and has the chance to attract interest from other clubs if he is able to show impressive performances during his loan spell.
