Milan want Real Madrid ace Kaka to return to the club, but they have armed themselves for battle with Inter, who are also keen as a transfer battle is sparked.
Panorama.it reports the Milanese clubs will fight each other for the Brazilian, who looks set to leave the Bernabeu with a January exit looking likely.
Reports have linked Inter with Kaka, but they have treated them with short shrift publicly.
Privately though their interest remains high and good relations with Jose Mourinho could tip the scales in their favour.
