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.
It looks like Conte will be able to convince most of Napoli players to stay, but not Osimhen and Kvaratskhelia. Farbizio Romano reported that Osimhen will leave this summer, and Kvaratskhelia also received an offer from PSG. If these two players leave, Conte's efforts to boost Napoli performance so that they appear consistent next season will be very difficult.
Conte seems to have to update his list of target players to be prepared if the two key players leave. The quicker the process, the more time Conte has to prepare a strategy and adapt. Apart from all that, I think next season Napoli will be able to finish in the top four of the Serie A standings and get back on track, Conte has good bargaining power as a manager.
If Napoli releases Osimhen and Kvaratskhelia then they will automatically be able to recruit other expensive players from the sale of these two players. Conte reportedly really wants to recruit Lukaku from Chelsea. Conte actually has to build a solid foundation first, where last season Napoli was very chaotic when they were handled by three different managers in one season.
