First of all, I would like to share the odds for next season's winner:
I think that Roma and Milan are destined to do great things this year. They are two teams with two great coaches who can truly work magic.
It will just take a little patience and maybe we will see their teams at a high level, obviously giving them time to do their job
For Inter I will agree thsg we can expect a lot from them but with Roma I cannot be sure or even to think of it, I will rather anticipate Napoli than to think or Roma doing great things this season. My biggest expectation will be with Inter Milan, they did not have the opportunity to do some really mind blowing things last season, they may want to utilise the opportunity they will be having this new season. If Roma turns around to do better then good for them, by then they should have their inconsistency fixed but until then I still trust Inter Milan the most.
Napoli did something extraordinary last season in the Italian league, and we would like to see them continue that touch of progress and creativity in the coming season. Perhaps we are now seeing in them the same winning tendency that the golden boy of the Napoli club was able to do so well long ago. You are right that Inter Milan did not have the opportunity to do anything extraordinary this season, but Juventus Football Club changed managers with them earlier in the season.So, depending on the direction of these teams, they could have extreme competition with Napoli and Napoli will be among the best competitors.
