From the match statistics this season it's true, but of course we also can't make it look like it's easy for Napoli because regardless of anything qualifying for the last 16 in the Champions League means that the club has more strength and can be said to be good enough to see conditions like this of course there will be some other comparisons to think about.
I wouldn't take it as if it were easy for Napoli even if on paper they are the favourites.
In the last 16 round of the Champions League, all teams must fight well so that they can more easily face their opponents at home or away. Because it is an effort so that the team is not easily eliminated and can advance to the next round. This season Napoli is indeed one of the favorite teams to provide more fierce resistance in the Champions League so that there is a bit of different competition this season in the Champions League, although I am also still not sure that Napoli will win the Champions League this season.
