"What happened to Barca was never going to happen to us, we're Real Madrid", said the Brazilian, channelling Madrid's usual self-confidence, which has not waned even following a dismal domestic campaign, which has seen them drop down to fourth in the Liga standings, 15 points behind leaders Barca.
And they also thought Madrid were rightly awarded a penalty when Mehdi Benatia fouled Lucas Vazquez in stoppage time.
Juventus goalkeeper Giannluigi Buffon was then sent off for remonstrating with the English referee, which led to protests from his teammates.
Madrid had won 3-0 in the first leg in Turin last week, when Ronaldo scored one of his two goals with an fantastic overhead kick.
Tuttosport reads "Not like that" as they rue the fact that an "immense Juventus" were eliminated from the competition.
It was Juventus that got a rather surprise early opener in the 2nd minute as Sami Khedira produced a attractive lofted cross into the box, where Mario Mandzukic rose highest to head the ball straight under the crossbar and beyond the goalkeeper to make the scoreline. 0 - 1.
The visitors would have a second three minutes later if Gonzalo Higuain hadn't wasted a golden opportunity in front of the net, much as he did in last season's Champions League final between the same two clubs.
Juventus keeper Gianluigi Buffon was sent off for his protests, and Cristiano Ronaldo stepped up to send Real through to the last four for an eighth straight year.
But Los Blancos kept going until the end and Ronaldo's late goal was just about warranted.
The closest Real Madrid came to scoring in the first half was a shot in the final seconds by Rafael Varane that hit the cross-bar.
One of the biggest shocks in European football history looked a real possibility when Blaise Matuidi took advantage of Keylor Navas' dropped cross to make it 3-3 on aggregate just after the hour mark.
Massimiliano Allegri, Juventus boss: "The penalty, the referee saw that and gave the penalty. We could've scored five or six goals tonight, so we ought to be proud". For the penalty, my heart was beating hard, but I tried to stay calm. And especially you need personality to referee a game like this. We've lost - there's not much more to add. "There was a lot of confusion", he was quoted as saying by Juventus' website.
'We should face and we did everything possible to go through, ' he said.
