Kaka: 'Ronaldo was the best I played with'

Former Brazil international Kaka has hailed ex-teammate Ronaldo as the best player he has ever seen.

The 32-year-old played alongside the legendary Ronaldo for the Selecao at the 2002 and 2006 World Cups, and the attacking midfielder talked up the ability of the former Barcelona and Inter Milan star.

"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 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."

The 38-year-old Ronaldo recently hinted at a comeback in the United States.
