The Champions League games against Real Madrid will provide some answers for Juventus boss Antonio Conte.
The two sides will face each other next week with the Old Lady needing a result after draws against Copenhagen and Galatasaray.
“I think it will be a nice challenge for us to go and compete with them at the Santiago Bernabéu, as well as at home,” Conte told UEFA.com.
“It's a very important test for us. Madrid are arguably one of the most ambitious teams. We're facing a club that really want this title, because of their history and their hunt for a tenth title.
“It will tell us how well our development is going.”
The tie will also see Conte face up to Carlo Ancelotti, the Real Madrid boss who coached the former midfielder in Turin.
“Juventus are very motivated and very well organised, with quality players,” Ancelotti commented to the same site.
“They have played together for three years under the same Coach and it's a well-structured club.
“They've signed some important players in the summer, like Fernando Llorente and Carlos Tevez who have given the team some extra quality.”
Real have a 100 per cent record in their group.
