"I know that he's been a top player for a number of years. I watched him grow up in Sao Paulo. He went to Manchester and played in front of the incredible supporters they have there against some really tough opponents and he never flinched," said Ronaldinho on his compatriot's performance at Old Trafford in the UEFA Champions League last term.

"He was the best player on the pitch, he kept going forward, and everything he did was full of finesse. He looked capable of scoring a crucial goal every time he was on the ball. Kaka has become a real all-round player, no doubt about it."
