I believe Osimhen no longer feels at home at Napoli or Napoli management needs fresh funds to bring in other players and Osimhen is the victim for all of that.
And there must be another reason why Conte really wants to bring in Lukaku. Maybe because Conte has also seen that the club wants to let Osimhen go. And maybe if the club has no intention of letting Osimhen go then Conte might not want Lukaku so much. but currently the scenario is as if Lukaku is expected to come and Osimhen is expected to leave there.
It's possible that if the price isn't too high, Osimhen could be bought by another team, but talking about Lukaku, Conte should be able to look for other options if in the end he can't bring Lukaku to Napoli and fill Napoli's main squad for the new season, I think Conte needs to look at it. other players who are young and more productive because the competition is quite tight next season, Conte should also focus more on recruiting young players to be able to play according to his wishes because many teams are starting to recruit young players and even coaches for a new breakthrough.
