Last year Juventus was very lucky and apparently they won the title.
They won most of the matches with 1 goal scored and most of the times this goal was lucky.
i have faith in Napoli this season. They made some good signings that can be proven valuable.
This is not luck alone for Juventus.
Juventus is one of Italy's strong teams, they have won many prestigious trophies. So, it is not luck for Juventus but it is hard work. I believe in Naples. Hopefully Napoli can compete with other Italian clubs for this season.
