Claudio Bellucci struck twice, while Antonio Cassano also was on the scoresheet after another inspirational performance.
Mazzarri said: "We are going to fight it out with everyone in this last month and will then see where we end up. We are in there and hope to challenge Fiorentina. If Antonio Cassano keeps playing like this, then anything could happen."
