Chelsea have put a big-money offer on the table for Brazilian playmaker Kaka, AC Milan vice-president Adriano Galliani said Sunday, without giving further details of the proposed deal.

"An astronomical offer has come in from Chelsea for Kaka," Galliani told Italian newspaper La Stampa, adding that club have also expressed interest in the club's World Cup winner Andrea Pirlo.

Despite failing to qualify for the UEFA Champions League, Galliani insisted the Rossoneri have been continuing to strengthen their squad and increase players' salaries.

"This means we'll be 50 million euros (78 million dollars) in the red," he said, adding: "All we would need to do in order to wipe out our debts is sell Kaka and Pirlo."

AC Milan have been linked with various players in the close season, including Barcelona duo Samuel Eto'o and Ronaldinho, and Arsenal's unsettled star Emmanuel Adebayor.
