With Milan in talks with Barca over Ronaldinho and Gianluca Zambrotta, Laporta intends to put forward a mega swap offer to convince the Rossoneri to part with their Brazilian ace.
Laporta would be willing to offer Ronaldinho, Zambrotta and Deco - plus £15 million cash - in exchange for Kaka, which would effectively be the richest transfer in history.
Kaka has made it no secret his desire to play in Spain and Milan's failure to qualify for next season's Champions League will unsettle the Brazilian, who has lost his status as the world's best player in the last 12 months.
