Brazil qualified for the Confederations Cup semi-final by beating a 10-man USA team 3 – 0 on Thursday.
Felipe Melo, Robinho and Maicon secured the three points that lift Dunga’s men to the top of Group B with Italy, in action against Egypt in Thursday’s other game, to come on Sunday.
“We played well but we want to play even better in the games ahead,” warned Manchester City striker Robinho.
“Against Egypt we didn’t play well in the second half but today we showed our real game,” added Kaka, while Dunga’s thoughts had already turned to Saturday’s final group game.
“When Brazil face Italy you never know what’s going to happen,” ventured the Brazil coach.
Egypt stunned the soccer world by beating the World Champions Italy 1 – 0 in their Confederations Cup encounter on Thursday.
Mohamed Homos was their hero with his 40th minute header enough to hand them a famous victory in front of 51,000 fans, but they also had goalkeeper Essam al-Hadary to thank for pulling off a string of fine saves.
Egypt and Italy are now level on three points in Group B with the Pharoahs favourites to go through to the semi-finals.
They face the United States on Sunday while Italy must play Brazil, who have two wins out of two so far.
Egypt coach Hassan Shehata said before the game that African pride was at stake and his team was bubbling with confidence after pushing Brazil hard in their gallant 4-3 defeat on Monday.
The African Nations Cup champions’ made one change from that match and it was an inspired move, with Homos replacing 35-year-old captain Ahmed Hassan, the country’s most capped player.
