Napoli coach Walter Mazzarri insists they didn't deserve defeat to AS Roma.

Napoli attacked throughout the match, but were beaten 3-1 at the San Paolo.

"Roma are an excellent squad and Erik Lamela is destined to be a champion. We knew the dangers that this fixture held for us," said the Coach.

"I could have asked for nothing more from my Napoli, as I'm happy with their performance. We have to accept the result. In football you win and you lose."
