Victor Osimhen is among the top 10 strikers in the world right now, so I disagree with you that Victor Osimhen isn't good enough for Arsenal to sign him. If Arsenal doesn't want to sign Victor Osimhen, just know that he's not Arsenal's top priority at the moment, or Victor Osimhen will not fit into Mikel Arteta's tactics at Arsenal. Arsenal shouldn't waste their time chasing Alexander Isak because Newcastle United won't sell Isak to Arsenal because Newcastle United still needs more quality players to be a threat to top clubs in the Premier League.
Victor Osimhen currently only needs a big club that can give him the opportunity to show more of his extraordinary skills as one of the best strikers. In the Turkish League he immediately became the top scorer last season. But it didn't really bring much attention to it. And I think he needs a bigger stage like in the Premier League or in Laliga. That way we will really see him getting a lot of attention for his extraordinary skills.
And I personally actually see Arsenal being quite suitable for Osimhen. It's just that I'm not sure Arsenal will want to pay Osimhen's fairly high release clause. But Osimhen doesn't need to go to Arsenal, he can also go to any other English team that wants him. Because it's not just Arsenal who want Osimhen's services.
