The Brazil international has struggled for both form and fitness since leaving for the Santiago Bernabeu in 2009 and is now seemingly on the verge of rejoining the Rossoneri

Kaka's agent has admitted that he is in talks with AC Milan over the Real Madrid man's possible return to San Siro.

Rossoneri CEO Adriano Galliani hinted on Wednesday morning that the club were interested in re-signing the Brazil international, who left for Los Blancos three years ago, and now the player's representative, Gaetano Paolillo, has confirmed that the deal is under discussion. 

"Yes, we are talking about him," the agent told Sky Sport Italia. "But I can't add further information at the moment."

Madrid paid a reported €70 million for Kaka during the summer of 2009 but the attacking midfielder has never managed to justify his lofty price tag, with his time in the Spanish capital having been blighted by injuries.

The former Ballon d'Or winner has been predominantly used as an impact substitute since the arrival of Mesut Ozil at the Santiago Bernabeu two years ago.

Madrid assistant coach Aitor Karanka intimated after Tuesday evening's friendly win over Real Oviedo that Kaka had been deemed surplus to requirements, with the club currently set on signing Tottenham midfielder Luka Modric.

Kaka, who has been capped 82 times by his country, has previously been linked with Ligue 1 giants Paris Saint-Germain, as well as Brazilian outfit Sao Paulo.
