It's too early to draw conclusions and say who will win and when. We simply have to enjoy the championship and decide who to support. I will obviously continue with Roma even though I know they can't do much more, but I will support them anyway. As for who I think can win, I think Juventus can do well this year, but as we were saying, it's too early to say.
Gasperini built up a very attacking Atalanta but in his two first matches with AS Roma, he won minimally with them. This means either he has changed his tactics - that I don't believe he changed, or AS Roma does not have enough good attacking players to play so attacking and score many goals. Another possibility is those players need more time to absorb the tactical philosophy of Gasperini for playing more goal productive.
Scudetto is a very ambitious target and if Napoli could win it last season with Conte, AS Roma can win it this season with Gasperini. Yes, they can but there are many matches till the season ending and AS Roma must work very hard to get Scudetto. If they want to win Scudetto, they must start to think of it now, work for it now as in Scudetto competition, any point drops can decide the title winner.
