There are so many players who have returned from their loan at Napoli now. The number of players has increased a lot and I assume they would loan those players again. Most of them are young players of course. Other than that we have witnessed Kim Min-jae signing for Bayern Munich as well. They paid 50 million euros for him. Napoli should use this money to sign a new centre-back. They should find a solid one as well after losing a great defender like Kim Min-jae as well.
Max Kilman and Josip Sutalo are the latest speculations that I can see on Transfermarkt now. But they were entered like 10 days ago.
I think, Napoli is not a club that often spends a lot of money to bring in players with great quality. Because the fact is, even though at this moment Napoli have been left behind by their great defender. But Napoli have just brought in forwards so far and thus, it seems that Napoli maybe not prioritizing too much to find a replacement for Min jae Kim for the position at center back. But yes, it is not too clear what Napoli will do for the next season as their main players like Osimhen also still in the team. Therefore, it is appropriate for Napoli to look for a great player for the defense position of course, at least to make the team performance more balanced in attack and also for their defense.
