Throughout his incredible career, no side suffered more at Cristiano Ronaldo's feet and head than Atlético de Madrid.
He scored a staggering 25 goals against Real's city rivals, preventing Diego Simeone's side from winning multiple Champions League titles.
On this day in 2017, he did exactly that with a stunning hat-trick at the Bernabéu.
The Portuguese legend showed off the full repertoire of his incredible finishing ability, planting three brilliant efforts past a helpless Jan Oblak.
The goals all but ended the clubs' Champions League semi-final tie as Real marched on to the second title of their three-in-a-row success.
The season was arguably the absolute peak of Ronaldo's powers as he also scored five against Bayern Munich in the quarter-finals and two against Juventus in the final.
Ronaldo would join Juve in 2018 and knock Atlético again in his debut season with, you guessed it, a hat-trick.
There's a reason – or several – for his status as the best player in Champions League history.
