#4 He is a more complete player than Lionel Messi
Cristiano Ronaldo is a right-footed player, but over the years, he has worked on his weaker foot to the point that he is almost adept in its use, while he is also arguably the greatest header of a football in history.
A breakdown of Ronaldo's 700 goals for club and country reveals that 442 (63.1%) came with his dominant right foot, 129 (18.6%) with his left, and 127 (18.2%) with his head, while two were scored with other body parts.
This goes in stark contrast with Lionel Messi who is extremely reliant on his left foot, with a staggering 83.5% (501) of his first 600 goals for Barcelona coming with his dominant leg, while 14.1% (85), and just 9.1% (55) goals were scored with his weaker foot and head respectively.
While he might not yet be truly ambipedal as players like Ousmane Dembele and Santi Cazorla, Ronaldo is more comfortable with both feet than Messi.
In addition to his brilliance in the air and use of both feet, the 34-year-old is also in pristine physical shape and athleticism.
