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.
Losing a great defender like Kim Min-Jae that Napoli must immediately get a replacement that is commensurate with him, because if next season Napoli do not have a strong defense it will make it difficult for them to defend the title they got last season. Although for next season there is no guarantee how the Napoli squad can compete with other clubs after the coaching chair has been replaced by a new coach. Rudi Garcia will start a difficult job next season because the burden he has is so heavy that there are many things that need to be evaluated before the competition starts.
The right option and must be realized immediately because the Napoli squad needs a player who can replace Kim Min-Jae, but for the first offer Max Kilman was rejected and maybe it will continue with further offers and for Josip Sutalo Napoli are not alone because several other clubs also want his services.
