Ronaldo the best player I have ever seen, says Kaka

Kaka has claimed former Brazil star Ronaldo is the best player he has ever seen due to the speed with which he could play.

Kaka played alongside Ronaldo for the Selecao and briefly during the latter's stint at AC Milan, which was blighted by injury problems.

Although the 32-year-old has featured in the same Real Madrid side as Cristiano Ronaldo and faced Barcelona's Lionel Messi, he maintains his compatriot could execute a move with greater speed and finesse than any other player.

"For me, the best players are those who are able to think of a play and execute it quickest and in the best way possible, and Ronaldo Nazario has been the best at that," Kaka, who began pre-season preparations with MLS side Orlando City on Friday, told reporters.

"The speed of thought that he had - and the speed he had to carry out his actions - were perfect. It was something amazing.

"I've thought a lot about other players before. I think he was a phenomenon."

Kaka, who claimed the Ballon d'Or in 2007, was part of Brazil's victorious 2002 World Cup campaign alongside Ronaldo.
