The former Blancos star can understand why the Portuguese has opted to end his nine-year stint in the Spanish capital and join the Serie A champions. Ronaldo will be presented as a Juve player on Monday after nine trophy-laden years at the Santiago Bernabeu that have also seen him become the Spanish club's all-time leading goalscorer.
Ronaldo is a very experienced player now, 33 years old so he knows and understands the situation very well," Kaka. "This decision to move from Madrid to Juventus, it's a very conscious decision. He knows it's time to move.
"He's probably thinking I achieved everything I could with Real Madrid and now it's time to do something different to keep motivated. "That's what moved him to accept the offer from Juve to change from Real Madrid to the Italian team."
Juve have paid €112 million (£99m/$131m) to sign the Portuguese and handed him a four-year deal but Kaka hinted it was money well spent for a player of Ronaldo's calibre.
Asked if the Italian champions were getting one of the greatest-ever players, he added: "I think so. Ronaldo, with his numbers, says that. Everybody who had the privilege to watch him play... in my case, I had the privilege of training with him every day for four years.
"I saw how professional he is, how strong he is, how motivated he is, how strong in his mind he is, and can see that he still wants to get to a different level. "I think Ronaldo will be remembered as one of the best players in the world."
