Napoli's season is threatening to collapse after the top four playoff.
"I don't look at the table and I never have," insisted Mazzarri. "We weren't sharp against Juventus last week, but this time we deserved to win. It was simply an off day for the referee and our strikers.
"Now we have to look ahead to Wednesday's game against Atalanta. What I am interested in is that the team plays good football, which is what we did. Sadly our lack of experience compared to Lazio showed."
