If Chelsea really can sign Oshimen, it should be a great solution. Chelsea has no strong striker, they got difficulty in scoring goals. Osimhen is a machine goal of Napoli, he already proved that he is one of the most productive striker in the world.
However, I still doubt that Osimhen really wants to join Chelsea. There is no something interesting in Chelsea, it is not a strong team anymore. Chelsea squad looks difficult to win any title, they only struggle to return to the top 5 of EPL standings. I'm sure it is not enough for a top striker like Osimhen, he must prefer to join a club that has a high chance to win prestigious titles.
Osimhen can really change the game of Chelsea but sadly, they can't have him now maybe after another 2 years in Napoli. He has yet to make any public announcement on his new contract but it won't be less than 2 years which we know that it's a long time that lots of things will have change by then. Chelsea will not grow past like this, buying any players at this point to me is financial abuse, ttey don't need any players at this moment, what they need is making sure that all the players in the squad are blend together, the is managerian problems and he need to do his work asap, change style and improve on how to make sure that players relationship in ball possessiveness is high.
There are teams outside and inside Premier League that didn't spend much or even half of what Chelsea has spent till date in the transfer market and they are Okay, playing well even when the lose, their win is more. This is what Chelsea need and not any signee to impress their fans that they are ready to do something, later they will go and concedes goals. They better reshape their games if they want to stay relevant and make it to Champions League next season.
