Winger Insigne had placed his future at the Serie A club in doubt last month when he said that an offer might come in for him that he "can't refuse".
But the 27-year-old has revealed he is ready to commit his future to Napoli having been at the club since he was 15.
"Renewal? I'm waiting for the president," Insigne, whose current contract runs until the summer of 2022, told Sky Sport Italia.
"For my part there's maximum availability. We both want to move forward together. I hope that the signing of the contract will come soon.
