I think a player like Osimhen needs to play in a better team. Can you become the best player in the world by playing for Napoli? This is almost impossible.
I think a player at the age where he needs to show his highest performance should be in a team like Arsenal or Bayern. It has a value of over 100 million euros, but they are not using its potential right now. I think there is no need for such a player for a team that cannot even be among the top 3 teams in the Italian league
Yes, I also agree that Osimhen's good performance will be a waste if he stays at Napoli for too long. Because he needs to try to play at a different level at a different club or in a different competition such as in the EPL or in Laliga. Actually, quite a lot of people have wanted Osimhen since last season. It's just that Napoli set a price that was too high which made all interested clubs prefer to withdraw slowly. Napoli without Spalletti is very different. But Napoli without Osimhen would also be worse. So I also understand why the club always wants to keep him.
We are talking about a value of 100 million euros. There is no point in keeping such a player in the squad when Napoli has the opportunity to earn such money. With this money, they can provide a great resource for the development of infrastructure football. They can transfer new players. They cannot achieve success in such a league with only 1 star player, they also take away the player's future.
I think if an offer comes from a good club, a transfer should be made
