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.
For me, retaining a player at this time is a good decision because the club still believes in his team, but if the chemistry between the player and the club is no longer good, it is better to let him go immediately because no matter how hard the coach tries, if the player feels uncomfortable at the club then his performance will not be optimal. Victor Oshimen does have problems and it seems like that is what is affecting his declining performance last season, but I don't know, it could also be because the coach is not suited to his playing style. I also see that the club is trying hard to sell this player, even going so far as to give a discount, which means it is true the club really wants to let him go.
