Napoli coach Rafa Benitez says he was upset with all the missed chances during the 2-1 win over Genoa on Monday.
The Partenopei produced a superb first half of football against Gian Piero Gasperini's side but failed to add to their tally with Jonathan de Guzman wasting a one-on-one chance in the 37th minute of the game.
And with Genoa restoring parity in the 55th minute, it was down to Gonzalo Higuain to keep his cool from the penalty spot to help Napoli move up to third place.
"We deserved the win but it was a close scoreline, we should have scored more," Benitez said after the game.
"Yes, I was angry out there as well, I can't be happy when I see so many missed goal opportunities.
"I've been in the game long enough to know that anything can happen when you don't close a game. But the three points are well deserved.
"But I should also look at the positives, the behaviour of the players who kept fighting for the win and their reaction after [Genoa] equalised."
Napoli won the game after referee Gianpaolo Calvarese pointed to the spot in the 73rd minute of the game as Benitez insists he prefers not to comment on dubious referee decisions.
"I don't talk about referees," the Spaniard said.
"If I do I would have to also talk about the red-card foul after 30 minutes of the game where the referee waved play on. We were 1-0 up and the game would have changed.
"This was a game where we had more than ten chances to score so one cannot summarise the game in one decision. With the only exception of the Juventus game I never spoke about referees in one and a half years.
"And I will continue to do so."
