Juventus defender Giorgio Chiellini has described Sunday's match against Hellas Verona as one of "the most difficult" the Bianconeri face.
Antonio Conte's men, who are currently nine points clear at the top of the Serie A table, travel to Verona in strong league form.
"Sunday's game is the most difficult we've faced in this period," the 29-year-old is quoted as saying by Football Itallia. "Verona are a solid team with plenty of enthusiasm and emerging players like [Juan] Iturbe and Romulo [Souza], who have played at high levels worthy of great teams this season.
"We're a different team to the one that won through a more dynamic and gung-ho style in the first year. We've grown a lot in these two and a half seasons. We've made important changes to improve, and the player's individual development has also been fundamental.
"We feel much stronger than the Juve of two years ago, but we have to prove it every Sunday. That's the challenge."
Juventus follow up their trip to Verona with a home clash against Chievo.
