Juventus coach Andrea Pirlo by how poor they performed in their 2-0 defeat to Inter Milan.
The result was never really in doubt at San Siro, as Nicolò Barella created one goal for Arturo Vidal and scored the second himself on a long Alessandro Bastoni ball.
“We got the attitude wrong from the start and when you don't have the determination to win the duels, it becomes difficult," Pirlo told Sky Sport Italia.
“We just didn't step onto the pitch, we were timorous, afraid of Inter's attacking play, so in our minds we only focused on defending and weren't even very aggressive with that either. We allowed Inter to take the initiative and they become devastating in those circumstances.
“Individual quality can only shine if you first match the opposition in terms of aggression and determination. We didn't do that and it showed.
“It's a bad defeat, we could not have played worse than this and it was unexpected, but we have to lift our heads and prepare for Wednesday and the Supercoppa against Napoli."
