Napoli coach Walter Mazzarri felt they deserved more after their draw with AS Roma.
The Partenopei fought back to go 2-1 up before a last-gasp Fabio Simplicio strike made it 2-2.
"We had our chances in the first half too, while after the break we made mistakes that we cannot afford, wasted too many goals and at the end were punished," said the Coach.
"We wasted an opportunity, which is not the first time it has happened this season, as we have dropped points along the way.
"Edinson Cavani seemed tired, so I replaced him with Ezequiel Lavezzi, who I thought could be more useful on the counter-attack. Unfortunately he's still not 100 per cent fit, which is why he couldn't start.
"Camilo Zuniga has incredible talent, but he was terrible in the first half. After the break he changed gear and scored a wonderful goal. It's a shame about the late distraction, but aside from that we also made too many mistakes in attack."
