Let's move on to the world cup. We were watching this weekend, and the countdown on to tomorrow's big knockout game between team usa and Belgium. One of the rising soccer powers in Europe. Paula Faris is outside the stadium with a preview. Good morning, Paula. Reporter: And good morning, Amy. The stadium behind me where team usa will learn their fate tomorrow. And they are not ready to go home. In fact team usa's coach is now telling the player's family here in Brazil to wait and book the flight for after the championship game. It's do or die for the U.S. Team against one of Europe's top up and comers. The Americans, who returned to the world cup only in 1990 after a 40-year absence, advanced out of the so-called group of death, stunning everyone but themselves. And they got out of this group, now anything is doable. But you need to understand that you have to raise the bar. Personal and as a whole team. And Belgium has the lead. Reporter: Now they face a young and hungry Belgium team in a sudden death round of 16 tomorrow. Belgium is a team steeped in soccer tradition. One of the founding 11 members of fifa, made up of players from Europe's top divisions. And unlike the U.S., which has so far had a win -- a tie -- and a loss. Germany going through! Reporter: Belgium won all three of their games behind one of the top goaltenders. And led by Eden hazard, the star attacking midfielder. Will they be ready? Do you think we'll see another level of intensity? Yes, you have been hearing all of their press conference sound bytes have been we haven't shown our true form yet. We haven't played our 100% capacity yet, even though we've had good games. We're not content. It's a great sign. Reporter: From sea to shining sea, the U.S. Team has been embraced like never before. We are very optimistic. Every day is a big step forward for jozy, and it's looking better every day. Reporter: And some potential good news for team usa, they are, quote, very optimistic that jozy altidore, their star striker, out for the last two weeks, the game against Ghana, confident he could be back on the field tonight, rather, tomorrow. As for the weather tomorrow, hot, humid, slight chance of rain. Another typical winter day here in Brazil. Yes, we saw that shot with people walking by on the beach with you and Julie foudy. It's tomorrow, 3:00 eastern on ESPN. And a dumb header on today as well.
