I agree with you. because I also don't think that Conte prioritizes Lukaku in this matter. It's just that even without Conte wanting to bring in Lukaku, we know that Osimhen is no longer comfortable there and has the potential to leave there. As a result of the problems that arose last season, the relationship between Osimhen and the club became strained.
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.
I am sure that Conte would like to keep all the forwards in the team, if he succeeds, then he will have very good attacking potential in Kvaratskhelia, Osimhen, if he can keep them, and Lukaku if he manages to rent or buy him. I think this could be one of the top attacks in Serie A, and I don't see any reason why Conte wouldn't want to achieve it. I see that PSG are very active in negotiations with Kvaratskhelia, as they also need a good striker, but Conte is ambitious enough to try to keep them all in the team.
