"Big challenges to come on the 30th!!!"
At the time of writing - two hours after it was published - the video has been watched 3.6 million times.
"He is the man I have to beat on YouTube," Ronaldo said.
"I want to beat him, watch out! My kids tell me I've become a YouTuber!
"Above all, I want to be close to my fans."
The footballer's channel crossed the one million subscribers mark within just 90 minutes of its launch. He was also the fastest YouTuber to record one million subscribers.

Those uploads have included collaborations with his partner, Georgina Rodriguez.
He's also posted day in the life videos.
