Brazil star Kaka trained for the first time with the World Cup squad on Tuesday after missing the previous session due to injury.

The 28-year-old playmaker, whose maiden season with Real Madrid ended in disappointment with no trophies, had been suffering from a left groin injury.

Brazil are due to play two friendlies on June 2 and June 7 against Tanzania and Zimbabwe respectively before traveling to Brasilia to meet President Luiz Inacio Lula da Silva's and flying to Johannesburg.

The five-time World Cup champions, who finished top in South America to qualify for the June 11-July 11 World Cup finals, will kick off their South Africa campaign against DPR Korea in Group G on June 15.

Dubbed as "The Group of Death", Group G also features 2006 semifinalists Portugal and African giants Cote d'Ivoire.
