He may be a Lionel Messi fan, but the Portuguese ace's son knows who's the boss in football.

There is no denying that Cristiano Ronaldo’s son, Cristiano Ronaldo Jr. (that really is his name) is cute. With his antics, from crashing his father’s interview in a full-body Spiderman suit, to showing off his football skills on the beach, he has grabbed the whole world’s heart.

Surprisingly, though, the five-year-old boy is an alleged Lionel Messi, that is according to his 30-year-old father, who revealed this bombshell to the Argentine during his 2014 Ballon d’Or triumph.

Nonetheless, CR7 Jr. does know who’s the boss, and recently admitted that his father stands head over shoulders above everyone else in the beautiful game.

In a recent video that has gone viral, the three-time Ballon d’Or winner’s little boy was asked on camera “Who is your father”. His response:

“The best in the world!”

This will go the extra mile in boosting Cristiano's confidence in the never-ending, sometimes volatile Messi vs Ronaldo debate, and which La Liga star is the best in the world.

Cristiano Ronaldo Jr. did also imitate his father’s famous “Sii” shout from the 2014 Ballon d’Or gala. Watch it all in the video below.
