The Selecao captain was delighted with his side's 5-0 victory over South Africa at Soccer City on Wednesday and insists they are ready to claim World Cup 2014
The Gillette Brasil Global Tour clash in Johannesburg was Brazil’s last before coach Luiz Felipe Scolari confirms his World Cup squad, which will be announced May 7.
And PSG defender Silva says the result will be a huge confident boost for a group that has come a long since Felipao took charge in November 2012.
"We close the preparations well, on a high note," Silva said. "If I'm not mistaken, in the last 20 matches we had 15 or 16 wins. That gives us a lot of confidence, a morale boost, a lot of peace so that we can relax a little in the next three months before the World Cup."
"I have no doubts that this groups is absolutely ready to be champion. We had a wonderful Confederations Cup, we closed our preparations now on a high note. Now we have to rest, play the championships that we have to play, because the World Cup we will do anything in our power to win."
Brazil will be grouped with Croatia, Mexico and Cameroon when the World Cup kicks off in June.
