“Yes, we talked about Kaka,” said agent Gaetano Paolillo after dinner with vice-president Adriano Galliani in Milan on Tuesday.
Paolillo left the club's offices after further talks on Wednesday.
“Did we talk about Kaka? Yes, but don’t ask me to say any more than that,” added Paolillo.
Brazil's Kaka left Milan for Madrid in a £56m transfer in 2009 after winning the World Player of the Year gong in 2007.
“Some loves never die, they just go round and come back again,” said Galliani as he hinted talks had opened with the player's representative.
