The promising 22-year-old insists that he would not join the Bianconeri even if they offered him a huge sum of money and warns that his club need a replacement for Edinson Cavani
The 22-year-old is regarded as one of most promising Italian strikers in Serie A, having rose to prominence playing in the lower leagues on loan to Foggia and Pescara.
The Partenopei attacker featured regularly under former coach Walter Mazzarri, playing 37 out of 38 league matches last year, and is adamant that he would not be swayed by a lucrative offer from rivals Juventus.
"I would not play with them even if they tripled my salary," he told la Repubblica of Juve. "I have a contract until 2017, I'm living a dream playing in Naples just now ... though I could evaluate an experience abroad."
Rafael Benitez took over after Mazzarri's departure to Inter and has already started to rebuild for the coming season with the signings of Real Madrid duo Raul Albiol and Jose Callejon plus goalkeeper Rafael, with reports claiming that Gonzalo Higuain could be the next to make the switch.
Insigne says that he is relishing the prospect of developing his game under the Spaniard and hopes that a player like Higuain can help fill the void left by Edinson Cavani's departure to Paris Saint-Germain.
"I lacked a little in order to win but now I hope to manage it, especially with Napoli," he continued. "The Scudetto is no longer prohibited, but no predictions. We will certainly fight with everyone.
"Cavani wanted the ball only for himself. Edi gave us so much and he will be missed. I hope he comes to be replaced with another strong forward but with different characteristics.
"The fans don't put pressure on me. It doesn't weigh on me to be a Neopolitan in Napoli. I think only of the good of the team.
"The balance of last season was positive, even if I felt a little sacrificed, but I thank Mazzarri. Benitez will help the system, we attackers will be closer to the goal and I will aim for 15 goals.
"He is a coach of international experience. He makes no distinction between the youngsters and the more experienced."
