Former Manchester United and Chelsea boss Jose Mourinho has won praise from Rivaldo.
The Barca icon admits he was happier working with Mourinho than head coach Louis van Gaal at Barca.
Rivaldo told AS: "With Mourinho I was good, he was very close, a better person, I understood him better than I did with Van Gaal.
"I played three years on the left wing and I was always a 10, not an 11. In a match with Atletico Madrid, I changed and he got upset.
"Then I spoke with Mourinho, who was an assistant, to clarify things."
