Inter is currently in a bit of a slump. I see Napoli on the rise. Juventus played some impressive football in the CWC tournament. They scored a lot of goals. They eliminated Real Madrid. They could be a team capable of competing for the Italian league title. Of course, how they start the season is also important. They need to start well and build on that. Napoli currently appears to be the frontrunner for the title, but other teams are also well-prepared for the new season.
Every team is preparing for next season. There have been many changes across all teams, and we can already see some strengths, even if they are still subtle.
I agree that Napoli is currently very strong and is still the favorite to defend their Scudetto title next season.
This contrasts sharply with Inter Milan. After their change of coach, many doubted that Inter Milan could improve next season, and I think that's perfectly understandable.
Several other teams are also worth considering, such as Juventus, Roma, and several other top Serie A teams.
