Talking about Napoli, basically I'm also not too sure that Napoli will have the same good performance as last season. Therefore, I think top teams like Juventus, Inter, Milan and maybe a few other teams could have the same good chance too if only to predict at the start of the season. Therefore, I personally cannot impose or convict just one team to have the chance to be the best next season. As a matter of fact, we cannot ignore the efforts these teams have put in this transfer window in building up their squads to be even better.
I don’t know about the final result, but Napoli always have a very good start to the season and the fact that they did not take the title a year earlier is only due to the fact that by the end of the season they were running out of steam. They may not repeat their success, but I'm sure that the first third of the season they will be either leaders or among the leaders. In general, in fact, Serie A in recent years has been as random as possible and it is very difficult to predict who will become the champion. I remember how a few rounds before the finish line the year before last, Inter was the favorite (and from the point of view of bookmakers, it was a clear favorite), but in the end, Milan became the champion.
