He said: "After Mark (Hughes) left and I don't think that (Roberto) Mancini had confidence in me. Going on loan to Santos was the best solution because, if I'd stayed at City, I would not have played in the World Cup.
"The loan was very successful. I recaptured my love of football, won a title and confirmed my place in the Brazil team.
"It was an excellent experience and they tried to extend my loan, but City had made up their minds to sell."
