The Brazilian full-back has hit out at Real Madrid for their treatment of his national team-mate and believes that he would receive much better care in Catalunya
The former World Player of the Year has struggled to secure a starting role or even consistent playing time since joining Los Merengues in 2009, having struggled with injuries and inconsistency.
The 30-year-old was widely linked with a move back to AC Milan in the close season, and the former Sevilla man is adamant that his compatriot should have departed the Santiago Bernabeu.
"If I were Kaka, I would have left Real Madrid a long time ago," the right-back explained to Esporte Interactivo.
"Because in my life, I love playing football, and if you take away from me what I love, I lose my sense of life. I am sad because I admire Kaka and I would not like to live through what is happening to him.
"He made it to where very few have - the best in the world, and now he has no respect from their owners. I think he would not be going through this situation at Barcelona."
The 29-year-old then went on to voice his admiration for former coach Pep Guardiola, who left the Camp Nou dug-out for a sabbatical, having become exhausted.
"Guardiola is the best coach I've had, the most complete, someone that you learn something from everyday.
"That's the difference with other coaches. He says: 'trust me and we will win the game'. So I admire him because he is a coach that can convince you that his is the way to win."
