Ronaldo is unsure of former AC Milan teammate Clarence Seedorf will move to Brazil this summer.
Ronaldo said: "I have not worked for Corinthians to bring Seedorf, but he is married to a Brazilian, speaks the language well and is very tempted by this adventure.
"But in the case of Seedorf or any other player of his age, what counts is the will of the player himself. At the end of the season he will be free from Milan, I think that the bids have been made and he is analyzing them.
"It seems that even Flamengo is dealing with Seedorf."
