France legend Zinedine Zidane insists that AC Milan playmaker Kaka 'has already signed for Real Madrid'. Both clubs have recently reached an agreement over Kaka, but the Brazilian sensation stated that he had no intention to leave San Siro. Zidane, who has just been appointed as the advisor of Real president Florentino Perez, assured shortly after that the deal went through. "Kaka has already signed for Real," said the World Cup winner, who played at Santiago Bernabeu for five years. "I would be happy if he were to take my number, the No.5, I would not be jealous."
