Cristiano Ronaldo Talks 'The Moment I Knew,' His 1st Sporting Lisbon Training

Cristiano Ronaldo has revealed on his Twitter account what happened in his first training with Sporting Lisbon in a video for Unscriptd titled The Moment I Knew.

The Portuguese star was still a boy when he joined Sporting in 1997 and quickly climbed the ranks before joining Manchester United in 2003.

Ronaldo, who has been with Real Madrid since 2009, revealed how he wowed the Portuguese side in his first training session when he was just 11 years old.

"I remember when I was in Madeira and Sporting Lisbon said, 'Listen, we want to see you better. You should come to Lisbon because we want to observe you,'" he said.

"And I remember my first training I did something and the players looked at me like 'Woah, can you do it again?' Even the coach!"

He was signed up and made his league debut for the side in 2002. The rest, as they say, is history.
