The Partenopei coach says he is unperturbed by what is said in the media and also praised striker Lorenzo Insigne ahead of the meeting with relegation candidates Pescara
The 51-year-old's team face bottom of the table Pescara on Sunday and, whilst he has confidence in his players, he says anything could happen in the match.
"I do not care too much about what others say about us, I just want to get the best out of my players and then see where we are at the end of the season," Mazzarri told a press conference.
"I am pleased that the players respect me, I have always been relaxed around them. They know how hard tomorrow’s game will be, as we know anything could happen."
The Napoli coach also took the time to praise Lorenzo Insigne, who went out on loan to Pescara last season and made a name for himself by helping them win promotion.
He added: "He is a mature lad who has understood that he must help the team and not care about what critics say.
"Not everyone realises that Serie A is a huge step up from Serie B, but that is why I think that Insigne has done so well."
