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.
As long as Napoli still has some great players like Osimhen and others, they should still have the potential to win in every match they face. What is a tough task for Conte is to provide instructions when competing on the field that can help the players win. Conte must retain his great players to keep Napoli's performance at the top of the standings. If Conte makes the wrong decision it will make it difficult for Napoli to maintain its performance.
If only these players are going to stay till next season because the transfer windows are open a s negotiations are on going for most of this players and like we all do know, osimhen has been longing to leave Napoli long before the end of the season, This moment he seem to be yet to find a good deal, if not I believe if his dream move was a success, he should have been in Chelsea by the end of the transfer window and not in Napoli anymore.
Even if it eventually happens that osimhen leaves Napoli, it's still very possible the team could end up winning the league title, it's not totally dependent on osimhen even with the fact that he's got a really huge role to play but it's always still possible a team will be able to achieve much even in the absence of a particular player but then, it has always been that for teams who had so much dependency on a particular player, they get to suffer much after the exit of such player a d that may be the case of Napoli if osimhen eventually leaves, but they may gwt to win the trophy again in the future not at the exact time he exited the team.
In the new season, it's not looking like the Italian league is going to be any competitive than it has been so Napoli may not even have to suffer much if they aren't improve and this is because the Italian Seria A isn't at the moment experiencing too many influx of new players or coach so there wouldn't be much changes around except for a few with teams like Napoli so the energy may still be like same as it has been.
