Real Madrid have put a €25m price-tag for any club who are interested in signing Kaka outright.
Milan have been in talks with Los Blancos in a bid to try and bring the Brazilian midfielder back to San Siro.
But according to Marca, the capital club have set a €25m price-tag on his head, a sum which has already scared off MLS club LA Galaxy.
The Serie A side will instead to try thrash out a loan-deal for the attacking midfielder, which Gazzetta dello Sport believe could be as long as 24 months.
Other reports in Italy however claim that the Rossoneri's vice-President Adriano Galliani wants a guarantee from Kaka that his wage demands will be extremely low, before negotiations progress any further.
The 30-year-old has already hinted that he would take a wage-cut to make sure the deal goes through.
And according to Sky Sport Italia, Milan would be willing to take him on-loan until June 2015 with €15m worth of wages spread over that period.
It would see Kaka giving up on €10m during that same time-frame, practically halving his pay.
