Napoli coach Rudi Garcia was happy with their 2-0 win at Salernitana.
Giacomo Raspadori and Elif Elmas struck for the visitors.
Garcia later said: "We had everything to lose and nothing to gain.
"We wanted to score in the first quarter of an hour and luckily we succeeded. In the derby the rankings don't matter, they almost cancel out. I liked the triangulations, perhaps we could have made some better choices at the moment of the last pass but Ochoa was good and Politano hit the post.
"If you don't close it, anything can happen, I only calmed down after the 0-2. That's okay, we did our job and now let's see what the others will do."
"We have always been calm, we have always worked well and we know we are an excellent team."
"Yes, we all defended together, acting as a team. We could have done better on some outings, but Meret spent a quiet afternoon and this certifies the positivity of his performance."
