The 27-year-old has been linked with the likes of Rubin Kazan, Zenit St Petersburg and Spartak Moscow.
“Napoli is my team, my shirt. The club that I wanted since I was a child, which I chose for love,” he told Corriere del Mezzogiorno.
“The Russian clubs? I have played against them several times and I scored versus Spartak Moscow and Zenit.
“I have no intention of leaving Napoli. But if the club decides otherwise, I cannot do anything.
“I’d stay forever, but they will decide whether to evaluate offers and if they propose them to me. I love my fans and I love Naples. I hope the club doesn’t do crazy things.”
