Juventus coach Max Allegri says they must use defeat to Genoa as a wake-up call.
Stefano Sturaro helped Cesare Prandelli's Genoa stun the champions-elect 2-0.
Allegri said, "I am actually happy for Stefano, because if anyone had to score against us, I'm glad it was Sturaro. He's a lovely guy and suffered so much, out of action for practically a year with that tendon injury, so he deserves it."
He added: “You can't play every game to the best of your abilities. I think, if anything, this defeat can do us good and wake us up. We thought that we'd already won the Scudetto, but that is not the case. We need another five wins and must now hope Napoli drop some points.
“It's impossible to win every game, I've said that since the start, so no need to make a drama out of it. We've played 28 games, won 24 and drawn three, so it's not that bad."
