The Brazilian star only renewed his deal last year, committing himself to Milan until 2011 for £3.75 millon-a-year. However, Bosco Leite, Kaka's Dad, is seeking talks over a new deal for his son and wants his wages hiked up to £4.25 million-a-year.
Bosco met with Real Madrid officials last week and was tabled terms worth £7 million-a-year.
Along with the new contract demands, says Corriere dello Sport, Bosco has also requested Milan to bring Kaka's brother, Digao, back from his loan at Rimini next season.
While considering Bosco's demands, Milan vice-president Adriano Galliani is ready to hand a more influential role to Leonardo at the club next season. The former Brazilian star is close to Kaka and his promotion is sure to please the Milan ace.
