Speaking to La Gazzetta dello Sport, Witsel said: "It's no coincidence that AC Milan rightly chose the 39-year-old Modric, and Italian champions Napoli chose the 34-year-old De Bruyne. Two absolute phenomena: they could have gone elsewhere, but I understand their decision and I'd like to emulate them.
"Kevin will have to adapt to Conte and Napoli, who play differently than City. But De Bruyne is a champion and will prove to be the best midfielder in Serie A. Modric permitting: Luka lives for football, he will carry Allegri's AC Milan. De Bruyne is exceptional; I expect at least 10 goals and 15 assists in Naples. He won't even need to speak to Lukaku on the pitch: they've had a great connection since their first years together in Belgium and they understand each other instantly, just a glance is enough."
Speaking about the title contenders, the Belgian midfielder added: "Napoli are the favourites. They are the reigning champions and on the bench they are led by a winner like Conte. Lukaku is a certainty and has strengthened on the transfer market. What a coup De Bruyne is, far from being at the end of his career... It would be great to find myself in Serie A with him, Rom, Modric, and Dzeko."
