"I saw a great Bayern in the first leg," he told Tuttosport. "They were well balanced, complete and devastating at times.
"That was no surprise for me because they are a European force, one on the same level of Barcelona and Real Madrid. But, besides the strength of Bayern, we didn't see the true Juventus in Munich. The players themselves knew that.
"I don't know if the comeback will happen, but I'm pretty sure that Juventus will prove to themselves and Bayern that they are a different team from the one seen in Germany."
The second leg will be played in Turin on Wednesday.
