Yes, you're absolutely right about that comment, because Napoli finished tenth the previous year, and no one thought their title claims were realistic. But Italy is such an exciting and high-quality place. Milan, who played poorly last season, may be champions this year. That's why we're watching an uncertain and high-quality Serie A. Inter looked like the favorites, but finished second and had to change managers, while Napoli played magnificently and won the title.
The Seria A is not like the French League where the winner of the Ligue One is highly predictable. Inter Milan was close to defend the trophy but surprisingly Napoli that had a poor previous season overlook them and won the League with a single point. If AC Milan has a good coach and can assemble committed players, we might see it winning the Scudetto. They have had some bad times recently and the fans need something to celebrate.
Serie A has always been spectacular and that's why it always manages to give that magic to the pitch, it's totally unpredictable, obviously there were years in which it always won the same teams like Juventus but now I would say that it's perfectly balanced
