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 .
How can you say Oshimen price tag has reduced because of his poor performance, is Oshimen playing badly? No Oshimen has been a key player in Galatasaray scoring 26 goals and 5 assists in his 30 appearance for the club. Is something you called poor performance, that's not true. Oshimen tag price reduced because he is not playing in top league but he can perform well in any league.
If Chelsea can get him It will be good for them, they need a striker like Oshimen to improve the team. Manchester United do not have a chance to sign him, because Manchester united won't be playing in the champions league next seaon, and Oshimen is a champions league player. Is only Chelsea and Arsenal stand the chance to sign him.
