Actually looking at what they did especially after relinquishing the Italian Cup then the focus must be on both although it's still very risky for them but i think they will still try to appear in Serie A and the Champions League.
Well, Napoli would definitely compete but I doubt they'll be able to win either of the champions league or Serie A. They're just not good enough this season to win either of those trophies.
With the kind of form they ended last season with, it was obvious to me Napoli was going to struggle this season. They really struggled towards the end of last season after they won the league and I knew they'll take that form into the next season and the have.
It happened to Inter Milan, then AC Milan and now Napoli. When these teams when the league the previous season, they mostly flip the next season.
Even if Napoli was in form, I doubt Inter is in the mood to let anyone go above them and win the Seria A this season.
