Robinho scored two goals and Kaka added another as Brazil easily defeated Tanzania 5-1 Monday in its last warmup before the World Cup.
Robinho scored first with a shot from inside the area in the 10th minute and added to the lead with a header in the 33rd at the National Stadium in Dar es Salaam, Tanzania.
Substitute midfielder Ramires scored his first two international goals in the 52nd and in injury time, while Kaka chested in a cross in the 76th.
"There is still something missing. But we still have a week to go before the opener and we will work to get better," said Kaka, who came into the match nursing a thigh injury but played the entire match.
Tanzania's lone goal was scored by Jabir Aziz from a corner in the 87th.
Brazil started the match with all regular starters with the exception of goalkeeper Julio Cesar, who is nursing a back injury and didn't even travel from the team's training camp in Johannesburg.
Brazil is in Group G at the World Cup and starts its campaign against North Korea on June 15 before facing Ivory Coast on June 20 and Portugal five days later.
With Tanzania President Jakaya Kikwete watching on, Robinho gave Brazil a 1-0 lead with a low shot from inside the area after a through ball from Kaka. He found the net again with a header after a cross by left back Michel Bastos.
Ramires eluded one defender before dribbling into the area and scoring his first international goal. Kaka made it 4-0 from inside the six-yard box, receiving a cross from Maicon and turning the ball into the net with his chest.
Ramires' second goal was a header into the far corner in injury time against the 108th-ranked Tanzania.
Dunga made six substitutions and tested a new formation in the second half, with right back Daniel Alves replacing Elano in midfield in a more attacking setup.
Tanzania: Jumanne Mwalami, Shadrack Issajika, Stephano Mwasika, Nadir Haroub, Kevin Yondar, Erasto Nyoni, Mrisho Ngasa, Abdulrahman Mohammed, Mussa Hassan Mgossi, Nizar Khalfan, Kiggy Makasi.
Brazil: Gomes, Maicon, Juan, Lucio (Luisao, 46), Michel Bastos (Gilberto, 46), Gilberto Silva (Josue, 46), Felipe Melo (Ramires, 46), Elano (Daniel Alves, 60), Kaka, Robinho and Luis Fabiano (Nilmar, 78).
