"As you know, I look at the performance beyond the result," Mazzarri told Sky Sport Italia.
"Football is based on incidents, which some weeks go against you. Since I arrived, the plan was to improve this side and grow their confidence, which I'd say is succeeding.
"Paradoxically, we played better tonight than we did when beating Fiorentina 2-1. We laid siege to Roma in the second half, but it never went in and at that point I realised we were never going to score a goal tonight."
