Victor Osimhen has been a fan of Chelsea from when he was still a kid in his native country of Nigeria. He's supported the club when he's never dreamt of playing football in Europe and playing for Chelsea now will be a dream come true for the young lad.
However with Osimhen's current high performance in football he doesn't need to join a club that's not gonna give him UEFA Champions League football. He's one of the hottest strikers in Europe at the moment so it'll be more advantageous to him now if he joins a club he can have the privilege to showcase his talent to the world by playing in the Champions League
I personally feel he needs to join his dream club as soon as possible but right now situation is not good at Chelsea with due to having poor position in league table and going to be overhauled by new coach things looking uncertain he needs to wait for one more season and just enjoy his best time at Napoli which is now also have new coach after this if in next season things will be change then surely he can join here otherwise playing with his current club and having good performance and experience is also important for him most chances now Chelsea will fight back, and we will have better things in next season then joining and giving his best for the dream club could be more entertaining and better for the lad.
