Looks like Napoli is really close to singing 2 players.
kevin de Bruyne and jonathan David can sing for Napoli really close.
Looks like their president is trying everything to keep Conte, who manifest the interest in going away.
The deal is still not confirmed, his contract will expire next month, still 1 month in his hands for exploring new opportunities & making the final decision. On the other hand, Conte was promoted to UCL after winning the Serie A cup, now he needs to rebuild his squad and search for some fresh blood for the upcoming UCL challenge.
De Bruyne could be a good asset for Conte, since he has potential experience and playmaking skills.

On the other hand, Bruyne already expressed huge interest for Napoli cause, his compatriot Romelu Lukaku inspired him a lot. he is ready to discuss about his 2-year contract with Napoli.
If you talk about Jonathan David, his move is still uncertain. This canadian striker is set to leave Lille as a free agent, he has already connected with Napoli, Juventus, Inter Milan, Liverpool, and Barcelona. I've heard a rumor that Napoli is offering him a 5 year contract, but I haven't heard any progress to finalize that offer. While Bruyne's move to Napoli seems to be very progressing, David's future destination is still undecided
