Although Galatasaray have benefited from him for a season, the club's financial situation wouldn't allow such a transfer. This has never been rational for Turkish clubs.
Everything is not clear, but I hope he doesn't go to Saudi Arabia first. It would be a bad mistake if Osimhen came to Arabia for the current age. But if the goal is money, it is not a problem.
So far osimhen still shows extraordinary sharpness in scoring goals, so I think there will be many big European teams that will try to re-recruit him next summer, although indeed galatasaray has the financial strength to keep osimhen but I think osimhen has bigger dreams to play in the big European team next season, even I think his departure to the Arab league is very unlikely to happen, because if he wants of course he will agree to the proposal submitted by Al Ahli before he chooses to be loaned to galatasaray previously.
Chelsea still doesn't seem to stop looking for young talents at the moment, Quenda has been confirmed to join chelsea next season with a 7-year contract with an option to extend 1 season, in my opinion it looks like chelsea is currently starting to change their foundation as a team that previously liked to recruit star players, but now is starting to try to build a team with young players.
