maybe it's too early but there's nothing wrong if everyone has speculation about Osimhen plans for a move because he is a quality player in serie A so teams from other leagues will definitely be very interested in recruiting him. In fact, I'm sure that at the end of the season there will be several teams that will make offers to Osimhen but Napoli has a contract with Osimhen until next season so for this season and next season Osimhen is certain to stay at Napoli except when Napoli has plans to sell him and looking at the current conditions Napoli management prefers to keep the player as long as they don't have a replacement player for Osimhen he will even offer a contract extension when his contract expires and I guess that Osimhen will reject the offer of a contract extension.
the EPL is a good choice for every top player because being in the EPL can give you much higher popularity to win prestigious titles but you still have to get the right team because if you just join a team like Chelsea it seems like it will only be in vain or it's better to choose to join with Arsenal.
Left two three months later before window transfer opening and too early speculation talking about Victor Osimhen's future, he has contract left with Napoli until June 2026 and left two years later he will stay with Napoli. I think Napoli will try to get best offer from many teams interested with Victor Osimhen without care which one the top team or not if can give expensive fees transfer will be prioritize by Napoli.
Actually Premier League is the best place or competition for Victor Osimhen but there are only two clubs interested with him Chelsea and Manchester United, I don't think very good ideas acceptable both team offering with potential absent playing in Champion League next season and will make experiencing career decline.
