AC Milan midfielder Kaka is relishing the prospect of taking on Atletico Madrid in the last 16 of the UEFA Champions League.
Milan host Atletico at the San Siro on Wednesday night and Kaka revealed in a Twitter question and answer session that the mood in the camp was confident after Sunday's 1-0 triumph over Bologna, in which Mario Ballottelli scored a wonder strike.
Kaka has made 22 appearances for the Rossoneri this season, scoring six goals, and he is pleased to have had a sustained period of time in the first team, after a number of years blighted by injuries.
Kaka said: "After the win against Bologna, we are confident and ready for Wednesday."
In the Twitter chat, the Brazilian also confirmed he still had aspirations to compete in the World Cup in his home country.
He added: "I'm doing everything to not miss the tournament. We will see if I am a part of the list of players called up to the squad in May."
