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.
It seems bookmakers priced Inter very high because of their squad's quality. They have a good squad with pretty good composition, and can fight against Napoli for the title race. However, they're not being coached by Inzaghi, which is really doubtful me they can meet my expectation.
Yeah it's solid odds for them at the start, but i must admit they're not strong enough by having Chivu on their side.
