Petkovic insists the Serie A leaders are not unbeatable.
"It's true the Bianconeri are close to the Scudetto, but there is no such thing as an impossible game. Nobody is unbeatable, not even Juventus," said the Coach.
"We already put Juve under pressure and knocked them out of the Coppa Italia semi-final. We must never let up the intensity for the full 90 minutes and ensure we don't let them play at their best.
"Even 100 per cent is not enough against Juventus, so we have to give 150 per cent. I really admire Antonio Conte, as he is one of the best Italian Coaches with such grit and determination."
