The Portuguese surpassed himself with a breathtaking overhead hit from inside the box to help put holders Real Madrid closer to the semifinals. "I jumped very high and it's a goal that will live long in the memory".
Having opened the scoring inside three minutes, the Portugal captain was at it again with an unforgettable bicycle kick in the second half.
"He has done everything here", tweeted former Real teammate Alvaro Arbeloa after the goal, which even prompted Juventus supporters to rise to their feet in applause.
Ronaldo responded by putting his hand to his heart and giving a slight bow of gratitude to the crowd. They realised that this was a moment to appreciate what they'd just seen, and to put their side's nearly certain elimination to one side.
"A lot of the Juventus fans stayed behind to applaud Ronaldo".
"I am like everyone", Zidane said at a postgame news conference.
Should he continue at this rate, a third straight UEFA Champions League final triumph could loom, though Ronaldo was in no rush to say as much. You don't win three Champions League titles in four years by accident. While one wrote, "When Zidane does this, you know you're good", another wrote, "How do I explain this to my unborn children?"
Such was the brilliance of the strike that Juventus fans stood up to applaud the goal that probably ended their hopes of going through. "It's attractive. You don't see that everywhere". I think we deserved to score at least one goal, but we faced a very strong and well-prepared team and we're sorry that we lost in this way.
Real Madrid manager Zinedine Zidane's reaction said it all. It's for this reason that Zlatan Ibrahimovic's debut goal for LA Galaxy last week was so widely publicised - because it was indicative of the outrageous skill with which he has become synonymous over the years.
