He said: "It's a new Mazzarri, I stopped on purpose to cleanse myself of the past, I no longer want to be the one who talks about referees.
"Next time I won't talk about the referees either, the old Mazzarri is retired. I prefer to do as on Sunday and not come because I imagined we would talk about that.
"I would just like to talk about the team."
Mazzarri was referring to last week's home defeat to Inter Milan where he skipped the post-match press conference.
