I'm worried that if Napoli buys Lukaku, it won't match Napoli's expectations, and won't even have any impact on the team. In my opinion, it's much better to look for younger players whose stamina isn't a priority. If they force it, the big possibility is that Napoli will of course waste money on transfers. that happened, keeping Osimhen rather than having to sacrifice him just for an old player like Lukaku.
It's true that Lukaku has started to decline when he defended his country at the Euros but seeing him with AS Roma he looks like a good striker, he works hard, moreover Conte has also worked with Lukaku so he knows what a good game is for him and Lukaku might really suit him strategy, because they both had beautiful moments when at Inter they managed to win the Italian Serie A for the 2021 season and so maybe they will succeed in taking advantage of that at Napoli.
Lukaku is also still very ideal in the Italian Serie A so there is no harm in Napoli bringing him to repeat his sweet togetherness with Conte, especially since Lukaku is very experienced in Serie A and Napoli really needs experienced players at the moment.
