AC Milan midfielder Kaka has undergone a problem-free, routine medical at the request of Real Madrid, the Brazilian Football Federation have confirmed.

The 27-year-old is currently on international duty ahead of Brazil's 2010 FIFA World Cup South Africa™ qualifier against Paraguay on Wednesday, but was released for the medical tests in Recife earlier today.

Spanish media are speculating Kaka will join Madrid in a 65 million euro deal, where he will become the first of the new wave of 'galacticos' brought together under the leadership of returning club president Florentino Perez. If it happens, the transfer would be Real Madrid's second biggest ever after the acquisition of Zinedine Zidane in 2001 for 75 million euros.

A statement from the Brazilian Football Federation read: "The technical committee of the Brazilian national team attended the request of Kaka and the board of Real Madrid and released the player to perform the routine examinations in a clinic in Recife.

"The CBF had to make all the arrangements for the test through its Medical Department head Jose Luiz Runco, who accompanied the player during the tests."

Perez has reportedly established a 200 million euro war chest for players, vowing to create a "spectacular team" capable of overtaking arch-rivals Barcelona next season.

He oversaw the era of the "Galacticos" when he was in charge at Real between 2000 and 2006, when global stars such as Zidane, England's David Beckham and Brazil's Ronaldo were attracted to the club.
