#2 Winning the FIFA World Cup in 2002
While winning the World Cup should rank higher than any other achievement in world football, it will not go down as that high of an accomplishment individually for Kaka, particularly due to his minimal contribution in leading Brazil to the trophy in Korea and Japan.
Throughout the course of the tournament, Kaka represented the national side for a paltry 25 minutes combined, and was never named in the starting eleven. Still only a fledgeling 20-year-old, Kaka knew he had to work hard to achieve his goal of being a regular for his country.
His World Cup debut came against Costa Rica in a group stage match when he replaced Rivaldo in the 65th minute. He alternated between playing as a number nine and right winger, and looked sharp regardless of where he played. However, it was the last time he was seen on the field in that competition.
If the likes of Rivaldo, Ronaldinho and Ronaldo weren't in the squad, it would've been ridiculous to omit Kaka from the first team. However, with a team bolstered by world-class talent in every department, merely making the 23-man squad was an achievement on its own for Kaka.
