I never believed Napoli would win the Scudetto, but Napoli surprised everyone and won the Scudetto. Yes, some clubs have changed their coach, but they don't have a good squad depth to compete for the Scudetto next season. I believe Inter Milan and Napoli still remain the favourite teams to win the Scudetto next season, and it won't be a surprise if either Inter Milan or Napoli wins the Scudetto next season.
Bookmakers estimate the teams' odds exactly this way: Napoli is the favorite, Inter is the second favorite.
Napoli - 2.63
Inter - 3.75
Juventus - 6.00
Ac Milan - 6.50
As Roma - 11.00
The other teams have significantly smaller chances. But still, the main favorite has chances significantly smaller than even 50%, something around 35%, so we can assume that the season will be exciting again and the intrigue will remain until the last rounds. I wonder if Roma can displace anyone from the top 4? Of the "other" teams, they look the most promising.
