Kaka left the Rossoneri this summer to join Madrid after five successful seasons with the Italian giants.

Milan's decision to sell Kaka proved a bitter blow for supporters, who were reluctant to see the club's number one star leave.

"For what I have achieved at the club in the years I spent there, I expect a warm welcome from the Rossoneri fans," said Kaka in Milan today.

Madrid go into tomorrow's Champions League game looking to avenge last month's 3-2 defeat at the hands of the Rossoneri in the Bernabeu.

Kaka has warned his team-mates to expect another battle in Milan.

"It's going to be a difficult match," said Kaka.
