That's crazy! According to Fabrizio, Galatasaray and Napoli have a deal for the transfer of Osimhen. One of the most expensive and best strikers at the moment and he's moving to the turkish league. He will play in the CL also but the league is absolutely no challenge for him. Besides Osimhen, Galatasaray also got Icardi back from injury and Zaniolo from loan. They have a really strong team that can currently compete with the big players in Europe.
I cant understand why people are saying this is not a good deal for Osimen. It is a very good deal to me. He could haven gotten a better deal and gone to a bigger club in Europe top 5 leagues, but staying in Galatasarayis not a bad idea. The fans already love him, he has performed for them and proven himself to them. There is way less pressure from that team and he gets to play in the Champions league.
It is better to stay in Turkey than go to Saudi Arabia. Age is still on his side, and a couple more years in Europe isn't bad. After his contract with Galatasaray runs out he can go retire in Saudi if he wants to.
