AC Milan vice-president Adriano Galliani says Chelsea have made an "astronomical" bid for Brazilian Kaka.
The Blues have long been linked with a move for 26-year-old World Player of the Year and their boss is now ex-Brazil coach Luiz Felipe Scolari.
Galliani told Italian newspaper La Stampa: "We received an astronomical offer from Chelsea for Kaka."
Galliani also revealed the club have had interest in 29-year-old Italy midfielder Andrea Pirlo. Pirlo's agent has been reported as saying in the Italian press he wants his client to be given the same wage as Kaka.
But Galliani added: "For Pirlo, there have been many requests. But neither Pirlo nor his agent have come into my office and asked me for an improvement in salary."
Galliani says selling Kaka and Pirlo would immediately stabilise Milan's finances, with the club having missed out on a place in next season's Champions League.
"All we would need to do in order to wipe out our debts is sell Kaka and Pirlo," he said.
AC Milan technical director Leonardo told BBC Sport last month it was "impossible" for Chelsea to sign Kaka.
Kaka himself revealed to BBC Sport in April he would not rule out the possibility of one day playing for one of the big clubs in the Premier League.
