Next season the battle will be between Napoli and Inter Milan for the Scudetto I don't think any other club has what it takes to challenge them in the title race, apart from KDB Napoli has other good players that would help them to defend the title and KDB will just use his experience to create good scoring chances for the Napoli strikers. Inter and AC Milan are the other two teams that are making good moves in signing players but Inter Milan is the only team that can challenge Napoli from what I can see other teams don't really have rust quality players that can stop Napoli.
It shouldn't be so certain before the season starts. Napoli and Inter Milan are definitely the favorites to win the upcoming season's title. But we shouldn't underestimate the other teams in any way. I would also like to include AC Milan in this competition. Although their performance was not good last season and they don't have high-quality players to compete in the upcoming season. But the inclusion of Luka Modric in the AC Milan team will definitely be influential and they will play well. Luka Modric is an experienced midfielder of the present era. I think his experience will be effective on the field and in the dressing room. So it is unfair to declare Napoli or Inter Milan as the champion team before the season starts.
