When he first came to Manchester United, he got a reputation for being a future star who fell over too often whenever he got tackled! But he soon toughened up and won lots of three Premier League titles, one FA Cup and a Champions League title in 2008.
He became the world's most expensive player when he moved to Spanish giants Real Madrid in 2009. His time there was a massive success and Cristiano became a legend in the all-white shirt - winning four Champions Leagues titles and becoming the club's highest ever goal scorer. But he never seemed completely happy there and threatened to leave many times.
But none of his arguments with Real Madrid affected his performances on the field in a negative way. He was so good that he won the Ballon d'Or Award for the world's best player award five times!

He also made it big on the international scene. Although Portugal got knocked out of World Cup 2018 earlier than many expected, he led his country to victory at Euro 2016 despite getting injured in the final.
Ronaldo is the only player to have won the Champions League five times and Juventus will be hoping that he brings his winning mentality to their club.
