Not to be a kill joy but if Osimhen were to go to any English side, Chelsea shouldn't be on his list because currently they're a team without a structure and it's like they are failed project. Before Chelsea will come back to the team we know, they need more than a year to to do that. Believe me if Victor Osimhen were to go to Chelsea, he'd just be a shadow of himself, we know of players who are in Chelsea now that were superb in their former clubs but are not really living up to expectations like Nicholas Jackson, Moises Caicedo and Christopher Nkunku ( this one is so injury prone that when he recovers, he'd be of little to no value to the club).
 It would be better to set his sights elsewhere to either Liverpool, Man City or Arsenal where his potential will be maximized, even though Chelsea has always been his dream club, I don't think he'd be the guy to change the outcome of the world.
At the moment, Osimhen doesn't need a club that is rebuilding themselves, who aren't consistent, rather he needs a team who are goal oriented since he's still quite young.
