The top two teams in the 2012 Olympic men's basketball tournament are set to face off for a chance to win a gold medal.

Team USA and Spain will meet in the finals Sunday in London. NBC will air the contest live at 10 a.m. EDT. If you can't get to a television, you can watch a free live stream online by clicking here.

The U.S. is looking to win its second straight gold medal at the Games, and will have to do so by going through the same opponent it beat in 2008. Spain gave the Americans a tough test in Beijing, and are prepared to do so again.

The two teams did meet in an exhibition prior to the Olympics where Team USA won easily, 100-78. Carmelo Anthony led all scorers with 27 points. LeBron James added 25.

Spain probably has the most talent of any team in the Olympics, save the U.S. Their roster includes five NBA players, some of which are among the best in the league.

Brothers Pau and Marc Gasol lead the group. They are two of the best big men in the NBA. Serge Ibaka is also on the squad. He finished second in the NBA Defensive Player of the Year voting in 2012.

Spain isn't just the best team that Team USA will face in the tournament, but also the club that presents the biggest matchup problems for the Americans.

The U.S. has just one legitimate center in Tyson Chandler. Kevin Love is the second tallest player at 6-foot-10, but he doesn't play like a big man. Anthony Davis is 6-foot-10 as well, but he hasn't even played a game in the pros yet.

If Spain can get the Gasol brothers going, they have a shot at pulling off the upset.

NBA point guard Jose Calderon is also on the club. He and team captain Juan Carlos-Navarro give Spain a very tough backcourt too.

Prediction: The U.S. has won with good outside shooting and a balanced scoring attack in London. They made 18 three-pointers in their win against Argentina in the semifinals. If they can remain hot from the outside, Spain won't have an answer for them. Team USA has shown no signs of slowing down, and Kobe Bryant and LeBron James seem to finally be hitting their stride. They are favored by 21 points, so don't expect this to be as close as the last gold medal game.

Predicted Score: USA 109, Spain 82
