Playing in the Champions League is certainly a dream of all players included osimhen and isn't PSG more promising to appear in the Champions League every season because they do not have strong rivals in the league compared to EPL teams?
A big and highly sought-after striker like Victor Osimhen would not just be considering playing in the CL, he will want to join a team that can actually compete for it and prolly win it, Napoli might not guarantee a player CL football every season, but at least every now and then they find themselves in the competition, so Osimhen already knows what it is like to play in the CL, winning it should be next up on his mind.
Having said that, i would love to see Victor in the EPL, i know Chelsea seems like the only EPL team interested in him right now, and they are a team in transition, so winning trophies might take sometime if Osimhen decides to join them. We can only continue to debate on his future, but we'd find out what he will do in the summer.
