Juventus will outperform everyone this year, I'm not saying they can win the Scudetto but I'm sure they can get in the middle of the best teams for the top 3 places, and certainly have a good run in the Champions League, Inter can also definitely take back the Scudetto, I see it as bad for Napoli instead.
There will definitely be a great fight in the upcoming season in the Italian League Serie A. Although it is not possible to mention Juventus' name in the Scudetto fight right now, because they do not seem strong enough for that fight yet. The fight for the Scudetto may be between Napoli and Inter Milan. Maybe AC Milan can raise some chances in that fight. But I do not think they are strong enough for the Scudetto fight either. However, we can see a fight for a place in the top 4 between Juventus, AC Milan and Atalanta. Juventus may have a higher chance of winning this fight.
