Cristiano Ronaldo's 97th-minute penalty sent Real to the Champions League semi-finals in memorable fashion, going through 4-3 on aggregate against Juve after a dramatic 3-1 loss on the night.
English referee Michael Oliver awarded Real a penalty with the tie seemingly heading for extra-time as Medhi Benatia knocked over Lucas Vazquez, with Juve goalkeeper Gianluigi Buffon sent off for protesting on his last Champions League appearance.
Ronaldo stepped up to beat Wojciech Szczesny, leaving Juventus devastated after a remarkable fightback to get to 3-3 after their 3-0 first-leg loss.
'It was a penalty, they've told me it was a penalty,' Zidane said. 'I didn't see it. The ref awarded it and we can't change that, but I think it was a penalty.
'Cristiano is used to these situations. He doesn't feel pressure. He scored the penalty and we got the win.
'There is nothing left to say. We're in the semi-finals and we're happy with that. They played well but we were just average, the difference is we kept believing until the end. We deserved to go through to the semi-finals over the course of the tie and we can be pleased with that.'
