I won't support the idea of Osimhen going to Chelsea, at least not after the insult and disappointment Chelsea made him go through last summer. If that young man wants to have a good and exciting career in the premier league, he should sign for Arsenal if they come calling for his services. The move will benefit him and the club very well. Arsenal at present are more Ambitious than Chelsea and Manchester United , and I'm sure Osimhen coming to the premier league is not to come here and be chasing top 4 finish as top priorities, as Chelsea and Manchester United have been reduced to that in recent years. Osimhen need to be in a team that are hungry for silverwares but they are lacking that finishing touches to get the job done. Arsenal will still pay him well. Liverpool is also a good place to consider, should they want to discard Núñez.
It is not surprising that Osimhen is attracting so much attention now, he is currently leading the scorers race in the Turkish League and this is to his advantage, in the off-season he can choose a more suitable club for himself than Galatasaray, if you believe the rumors, he is interested in moving to Juventus, I think this is understandable because he is well acquainted with Serie A, and as for the Premier League, it is not yet clear how his game will go there, but this season has shown that he is able to adapt to different championships.
There was a period where he didn't do amazingly, which made people question him for maybe one month at most. Afterwards, he just started scoring like candy, every single game. Most recently he had a hattrick, and didn't even used the penalty, if he did, he would have four goals in the same game.
So, all the big teams are seeing how great he is playing at the moment and just imagine him at their striker position at their club and willing to pay 75 million to make that a reality. We should also realize how inflation impacted football world too, 75 million would have been an insane number back in the day, but these days we see multiple 75+ million deals every summer. This should not be impossible for some big club to get him, very cheap for them.
