For me, about Osimhen playing at Galatasaray it is something good because anyway, considering about the transfer rumors that previously happened about Osimhen's move to PSG, Chelsea, Arsenal and maybe some other top teams also from different leagues that failed and or did not really happen. So, if Galatasaray do not sign Osimhen it will be worse for Osimhen, because Osimhen is also no longer needed at Napoli because Conte did not include Osimhen in the Napoli squad this season.
With this case, then playing at Galatasaray remains a good choice for Osimhen because he has accepted it. Because after all, the Turkish League is also basically a competitive league and moreover, Galatasaray will also still play in the Europa League this season. Thus, there is no setback whatsoever about Osimhen because after all, at Galatasaray also only has the status of a loan player and of course, there is still a chance for Osimhen to join other top European teams when the transfer window opens again later.
Galatasaray is the remaining option for Osimhen if he wants to stay on the pitch. It wasn't a bad choice as long as he didn't get stuck there forever. At least he still has the opportunity to play in this one season and if his performance is good, then he will have the opportunity to be noticed again by big European teams. However, if he fails to shine there, then he will not have many options next season and it is possible that he will really end up in Saudi Arabia.
