“Juve have plenty of energy left,” Marchisio told Sky Sport Italia.
“I am not just saying that because of all the fitness tests we’ve done recently. You can tell we’re in good shape, especially in recent outings, despite some criticism on our style of football.
“Our team doesn’t run many risks and is clinical, which means over the last year we have matured a great deal.”
