The Belgian has overtaken Hamsik as Napoli's leading goalscorer.
Hamsik, now with Dalian Professional, told Il Mattino: “Dries is an extraordinary player and man. I know how much he loves the city and this shirt.
“He's already an icon for Napoli and Naples. He's happy with breaking the goal record and I'm happy that it was him who overtook me.
“He's a icon, just as Insigne and Callejon are. Napoli must be proud to have champions like them, who fight and have been pouring their hearts out for years."
