Last I checked Osimhen is still in Europe. He plays for Galatasaray in Turkey and he's performing very well there. He's among the top scorers in the league and he's on course to help them win the league for them. He's not in Europe's top 5 leagues but he's still in Europe and still has a contract with Napoli.
I think it's a good thing his market value dropped so it will be easier for the team to sign him. Chelsea are feeling the consequences of not signing Osimhen last summer. I belive other top clubs will go for Osimhen or even Chelsea might go back for him.
Osimhen's release clause has already decreased a lot as a part of his contract extension with Napoli. His price dropped so much not because of how bad his performance. It's to ensure his clause has sense price, and he can leave anytime.
I saw some top clubs such as Arsenal, MU or even Chelsea strongly linked to him. However, there's no concrete development about which club has contacted his agent to buy him out. I hope Chelsea will contact his agent, then sign him asap .
I see Manu as the strongest candidate for Osimhen. Chelsea did not buy players for such astronomical amounts after Abrabomovic left the team. I don't think they can either.
Arsenal or Manu can buy him. Manu is the strongest candidate because they have had terrible seasons in recent years.
They need to build a good squad for next year. Arsenal can also because Arsenal doesn't have very good strikers either. Havertz is both injured and has never been a player with a very good goal shot.
