The 27-year-old is thought to be close to completing a move from AC Milan to Real Madrid for a world-record fee, with some reports even suggesting Madrid's doctor is currently in South America to carry out a medical.

The issue did not seem to affect Kaka in last night's 4-0 World Cup qualifying win in Uruguay and Dunga is confident his key man will have both eyes on Wednesday's game against Paraguay.

Dunga said: "Kaka is an experienced player and is fully focused on the national team. You only have to see how he played in the Uruguay match.

"However, it is obvious that he wants to sort this situation out quickly.

"At the moment, Kaka is a man of Milan, but if he has to move to Real Madrid, he will have no problems with that."
