Ronaldo has now reached the 400-goal mark for Real - though one of these is disputed - and his goal-scoring feats are now getting so gargantuan that it's easy to lose any sense of scale; few can compare with his records.
The Ronaldo's opponent, who played their semi-final UEFA Champions League to close in on a third final in four years.
Zinedine Zidane described Cristiano Ronaldo as "unique" after his hat-trick in Real Madrid's 3-0 Champions League win over Atletico. "The team was phenomenal and to score three goals made it a special night".
Of Ronaldo's 52 career goals in the knockout stage, 13 of them have come in the semifinals, and he is the fourth player with a hat trick in this round - the first since Robert Lewandowski in 2013.
In certain games at the Bernabeu, some of the fans whistle him when he touches the ball.
Cristiano Ronaldo was known for his deadly pace and step overs that used to terrorize full-backs. It had been an up-and-down season for Ronaldo, who has 35 goals so far. Filipe Luis slipped as he tried to make a clearance, which saw Ronaldo latch onto the lose ball before firing it past Oblak. He is the only player to have broken the 100-goal mark.More news: Iraq PM: No US combat troops to stay in Iraq after IS
Zidane spoke after the match, which by the way is Madrid's 300th win in European competitions.
It was bad when Dani Carvajal went down injured against Atletico Madrid, but it's gotten even worse for the Merengues. However, we haven't won anything yet and we need to be just as on it as we always are. You could certainly say that we were the better side today.
