America were sort of unlucky, although in the second half Brazil were clearly the better side. The build up to America's second goal and Landon Donovan's finish were probably the best moment for either team in the whole game. Brazil didn't do anything really spectacular. They were just able to step up a gear when they needed to.
Here's a highlights clip but it only really shows the goals and some build up. I take it that's it's in Brazilian, judging by the strange jingle that's played every time Brazil score.
