Napoli showed an inconsistent graph so far and even though Napoli won in the last fight I haven't seen any sign of improvement I mean maybe it's just luck. This week on March 4 Napoli will face Juventus, this will be a difficult match for both teams we cannot predict who will win because both teams won in the last fight. There is a possibility that this fight will end up a draw because both teams do not target anything Juventus are safe in the 2nd place and Napoli need more effort to go up to the 5th place, so a draw may be fair to both teams.
not luck, I would say they faced a very poor team
let's say that at the moment Napoli is a strong mid-table team in my opinion
it's not ready to go to cup competitions, like the Champions League
maybe next year he will settle down better and can compete
