CR7 is the highest scorer in the Champions League, and with his two goals against Bayern he reached a milestone previously un-heard of.
The Los Blancos talisman took to social media to express his gratitude to fans and his team-mates after achieving the feat.
Ronaldo scored his first European goal since September last year in the 47th minute put Real on level with Bayern, before adding another just 13 minutes from full time.
He took to Instagram to thank the fans, team-mates and coaches after the milestone.
CR7 wrote the caption: “So happy with the victory tonight and to have reached 💯⚽ in European competitions.
A huge thanks to all my team mates and coaches. Without them this wouldn’t be possible!”
Ronaldo reached 50 European goals in April 2013 after making 96 appearances, although scored only once in his first 32 games for Manchester United and Sporting Cp.
The Portuguese skipper has however made the second half-century much quickly in just 47 games.
Cristiano has scored 97 goals in the Champions League, one in qualifying rounds and two in the European Super Cup.
