In his nine memorable years with Los Blancos, the 36-year-old scored and assisted goals at a frightening rate.
Ronaldo played 438 games across all competitions for Real Madrid and in that time, he found the back of the net an astonishing 450 times.
The Portuguese superstar also provided 132 assists, meaning he averaged 1.33 goal contributions per match - which is just mind-blowingly good.
Ronaldo scored 40 or more La Liga goals in two separate seasons as well, the five-time Ballon d'Or winner first achieving the extraordinary feat in 2011/12.

But while that's the case, we still need to appreciate just how good Ronaldo was in the very same season.
The free-scoring forward did actually manage to better his 2011/12 league output in 2014/15, though.
