Gazzetta dello Sport says Kaka was subjected to abusive chants from home supporters, a rare occurrence in Italy.
"It was all very beautiful," insisted Kaka at the final whistle. "I'm happy because Milan are still chasing Inter and Juve, and even for my two goals. In 2009 we are demonstrating consistency."
On his blossoming partnership with Alexandre Pato, Kaka added: "We are improving. With Pato, it is going very well and the second goal, really was very beautiful, it was created from an exchange between us."
