Kaka made his AC Milan return in yesterday's friendly win over Chiasso.
Kaka was handed the captaincy for the 4-0 win.
"Milan looked very good and it was a pleasure to play today," he told Mediaset Premium at half-time.
"I am lacking a little bit of match fitness and we need to improve, but we have what it takes to do that. At the age of 31 I learned a lot, as now I can choose my passes better and make fewer mistakes."
