Cuadrado did not let up replying, "You must be an example for everyone"

Ronaldo did not back down and responded, "I'm included too. We have to tell each other the truth, we played s***. This is a Champions League match, we need to have personality."

Trying to de-escalate the situation in the dressing room, Juventus boss Andrea Pirlo stepped in.

He said, "That's enough, let's go. That's enough, Cri. That's enough, Juan.

"We have to be calm and patient. We will continue in this spirit, but without arguing, with the posture of someone who wants to win."
