The 25-year-old Slovakia international is of the opinion that he is enjoying the form of his life, but says he's ready to take things up a notch and help his team challenge Juve
The Slovakia international has netted seven times in 15 Serie A games for the Partenopei, who find themselves in second place in the standings, just two points behind league-leaders Juventus.
"I believe that this is my best campaign up until this point of my career," he told Sky Sport Italia.
"I'm scoring a lot of goals, but also doing well thanks to the work of the whole side," he added.
"I'm happy to be at Napoli where we are re-writing history, this is the club who wanted me the most and we still have a lot to do and win," he said.
Napoli travel to the Giuseppe Meazza to face Inter, who are just two points behind the Partenopei in the standings.
"The league table says that we are the anti-Juventus, we are close to them after a great start to the season.
"If we continue on this path then we can go far."
