I also doubt that the squad that Roma has now can make it different next season, because Mourinho will need time to adapt. So I still choose Juventus
or Inter who will dominate Serie A next season, especially since both teams are still reinforced by several star players.
Maybe if there is no change in the squad Juve will be the favorites to win. Milan, Atalanta and maybe Inter. Their dominance will remain. If there is the addition of new players I don't think it will change much. But for the Serie A champions I'm guessing Juventus for next season. Their players look better supported by the new coach
It is difficult to predict which team will win the Serie A. title. Because the teams here are almost the same quality. There is a lot of competition for the title. Inter Milan, AC Milan, Atalanta, Juventus and Roma are all good enough teams. So it is not possible to predict which team will win the title before the start of the season.
