Mazzarri said: "I like to sum up the situation when everything has been said and done. I won't answer questions on what our season has been like before we complete the next four games."
The first of them is against Cagliari and the Partenopei need a victory to maintain hope of a Champions League spot.
"Since becoming a Coach, experience has taught me that ifs and buts get you nowhere in football.
"I am not thinking about the table. My only focus is Cagliari and I invite our fans to be fired up so they can cheer us on.
"This is how we must think for the next four rounds. We've got to expect the best from ourselves, then see where we end up."
