Napoli lost their last game to champions Juventus, to fall three points behind La Senora.
“The Napoli fans are unique and I am happy to have received so much affection,” said the Slovak midfielder.
“We must not forget the defeats to Juve and Dnipro, but instead learn from them and not make the same mistakes.
“Now we want to win in front of our own fans and are looking ahead to Chievo on Sunday. Scudetto? We can dream.”
