Gazzetta dello Sport says Galliani will have lunch with Perez and the future of Kaka is sure to come up.
Both Galliani and Milan patron Silvio Berlusconi have made no secret of their wish to bring the Brazilian back to the San Siro.
Meanwhile, Galliani expressed fears for the future of Italian football: "Italian football has turned from a luxury restaurant into a pizza place.
"The major problem remains that of the stadiums. If we go on like this, after the Germans we will be surpassed even by the French."
