Siena boss Giuseppe Sannino is convinced that there are six teams who could win the Italian championship this season.
Although impressed by current leaders Juventus, the tactician has told Sky Italia that this could be one of the most open Scudetto battles for some time.
"Juventus are a different team this term," Sannino, whose side lost 1-0 to the Old Lady earlier this season, commented.
"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."
Milan and Inter have struggled so far this term, the Rome clubs will face each other this weekend, while Napoli and the Bianconeri have impressed.
