Napoli coach Rafa Benitez says the win against Fiorentina shows that his side is quality.
The Partenopei produced another brilliant display of football to battle their way past Vincenzo Montella's side and move up to third in the Serie A table.
"We could have won with more comfort," Benitez said.
"We created 4-5 clear opportunities but we also suffered and fought until the very end.
"Winning was not easy against a Fiorentina team that tried a number of solutions to cause us trouble.
"We can still improve but we're showing our quality.
"We're confident and we know people will start to talk about Napoli.
"We said it weeks ago, we have to continue working in the same way we've been doing since the start of the season.
"Gonzalo [Higuain] continues to impress on the pitch and he's improving with the rest of the team. He's pivotal to us and he knows it.
"I am sorry for Lorenzo [Insigne] because he gives everything for the team. We will now assess the injury, hoping he will not be out for long."
