It was 2-2 after 90 minutes, but with 11 against nine the Bianconeri ran out 4-2 winners. In protest, Napoli boycotted the presentation of the trophy. Pandev and Andrea Dossena were awarded two-match bans for Serie A.
Mazzarri revealed just how angry he was at the final whistle and why the club locked down a media silence.
"There was a moment when I wanted to resign, and not in the heat of the moment either. However, this week I was at a 'Juventus stronghold' and the Bianconeri fans apologised to me.
"Valon Behrami was pushed for a blatant penalty that Rizzoli didn't see. Interpretations of the rules can happen, but we cannot accept that the rules are applied in two different ways. We are indignant - not with the opponents, but with these aspects."
