Real Madrid forward Kaka is expecting a warm welcome on Tuesday night when he returns to the San Siro to take on his former team AC Milan.

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.

Madrid go into Tuesday'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.
