Siena boss Giuseppe Sannino is convinced of a wide open title race.
Sannino believes as many as six teams are capable of winning the Scudetto this season.
"Juventus are a different team this term," Sannino said.
"You can see that the Coach, Antonio Conte, has made a difference to the team by the way they play their football.
"Nevertheless, I believe that there are six teams who can fight for the League title this year - the two Roman clubs, the two Milan ones, Napoli and Juventus."
