Brazil could be forgiven for regarding South Africa, a team ranked 70 places below them in the FIFA/Coca-Cola World Rankings, as accessible opponents in Thursday 25 June's FIFA Confederations Cup semi-final.

But if that was the opinion in the Brazilian camp it certainly was not showing on Wednesday as Kaka and Co prepared for their last-four date with the hosts at Ellis Park.

"It's always difficult to play the host country, they'll be especially motivated, that gives emotional support to the host team," said coach Dunga, who as a player was coached by his South African counterpart Joel Santana.

"He knows what he's doing," the Seleção supremo continued. "South Africa have improved from game to game, but we're ready for the challenge.

"They must be respected as they've made it through to the semis. South Africa are a competitive team with African characteristics - they are very fast and strong but we'll play our football and try to nullify their positive qualities."

Former Arsenal midfielder Gilberto Silva, a regular in the side that is also riding high at the top of the South American Zone of 2010 FIFA World Cup™ qualifying, echoed his coach's comments on the dangers posed by Santana's Bafana Bafana.

"For South Africa, playing against Brazil is a very important game," he said. "We need to be focused, we don't want to be surprised by them. We can''t start looking towards the final, we've got to win this first."

Holders Brazil are unbeaten since arriving in South Africa, having followed up their 4-3 opening-game win over Egypt with successive 3-0 victories over Group B rivals the United States and Italy.
