Cagliari were arguably the better team at the Stadio San Paolo and very nearly managed to upset Napoli, but the Partenopei managed to hold on and eked out a slender win courtesy of a 72nd minute strike by midfielder Marek Hamsik.
With title challengers Inter Milan and Juventus both suffering losses over the weekend, the Partenopei have managed to move to just within two points of the Bianconeri at the top of the table.
Unsurprisingly, Mazzarri was pleased with his players for grinding out the win as the Partenopei gather momentum in a bid to unseat Juventus at the top of the table.
"We had to score first," Mazzarri was quoted as saying by the official Napoli website.
"And we did that. I am satisfied with the performance of my players.
"I could not ask for anything better from this group and I am proud to train them.
"Now we have to think about our next game against Pescara."
Match-winner Hamsik echoed his coach's sentiments and expressed his joy at having been able to pick up all three points against a 'tough' Cagliari side.
"It has been a very difficult game," Hamsik told Sky Sport Italia.
"Cagliari put us in a lot of difficult, but this win gives us a lot of confidence.
"Edinson Cavani was missing, but we did everything the Coach asked of us and we were able to bring home the three points."
Mazzarri says he will now take one game at a time.
He told Gazzetta.it: "We really deserved this victory and Napoli are going through a fine period.
"It was a difficult game. We played well in the first half and just lacked something in the final third.
"The Scudetto? We'll take each day as it comes. Today [Monday] we saw just how difficult this league is and we will only know where we stand at the very end.
"Considering how strong Cagliari are, this has been one of the most impressive results for us. It was a great game with the ball kept on the deck throughout.
"(Eduardo) Vargas came on and played really well. He deserved a goal and just needed a bit more luck."
Cagliari boss Ivo Pulga found the defeat difficult to digest.
"If any team should have won that game then it should have been Cagliari," he told Gazzetta.it.
"We lost based on one incident, when we had been constantly attacking and embarrassing Napoli.
"We had five or six meaty chances to score, hitting the post twice. They had to defend for long stretches with tight man marking.
"What else can I say? I have to congratulate the players but I'm sorry for the fans. All I can say is well done to everybody."
