Bayern Munich players were very happy after the game at Santiago Bernabéu.
Following the clashes between Leicester City supporters and officers that preceded last week's quarter-final first leg between Atletico Madrid and the Premier League champions, authorities in the Spanish capital pledged to reinforce its police presence for Bayern's visit.
Questions remain over whether two of his goals should have stood - and that's an understatement, because they were both offside - but you can't take anything away from him.
Ronaldo has now scored 395 times in 386 outings for Madrid and has 518 goals in 711 club appearances in total.

He followed up the snapshots of the decisions with another Instagram post in his story that said: "One year of hard work, thank you referee, bravo".
Just what Ronaldo deserved - his goals may have been offside, but he was once again the hero.
Ronaldo's second on the night and first in extra time looked the more clear cut decision, while his treble-completing strike seems a little tougher to call.
"Sometimes when he doesn't score we wonder what's happening to him. He made a lot of mistakes and he left us out of the Champions League".

Victory also secured history on a collective level for Madrid as they reached the semifinals for a record seventh straight year. "But now I'm feeling good and the team has been playing really well, that's what's important".
His Real Madrid counterpart Zinedine Zidane did not want to discuss the refereeing but he claimed Bayern's second goal could have also been ruled offside.
"Maybe they will not whistle him any more", said Zidane in defense of his star man.
"The fans will always appreciate Cristiano for all he has done here".
