What to Watch For

Brazil Takes Aim at Third Straight Cup Title

Brazil has owned the Confederations Cup over the years, winning three times since 1997. It's taking aim at a third straight title and fourth overall this Sunday in Rio de Janeiro.

2013 marks the first time that Brazil has hosted the World Cup warm-up event. In the past, Brazil has won this tournament in Saudi Arabia, Germany and South Africa. But on Sunday, the South American powerhouse will have the advantage of playing at home in front of a raucous crowd.

Four years back, Brazil came back from two goals down to beat the United States 3-2 in the Confederations Cups final. In its three Cup final victories, the squad has outscored its opponents by a combined count of 13-3.

And with the Selecao set to host the 2014 World Cup a year from now, Sunday's result will have huge implications for the future. A win would raise expectations for next year's month-long tournament, while a loss could lead to some major squad changes, starting with head coach Luiz Felipe Scolari.

Spain Looking to Continue International Dominance

La Roja have been dominating the international stage for years now. On Sunday, the reigning World Cup and European champion can reaffirm itself as world football's top dog.

Vicente del Bosque's squad has won three of the past four FIFA major tournaments dating back to the 2008 European Championship. The only international title Spain doesn't have is the Confederations Cup.

The Spanish were upset by the United States in the semifinals four years ago in South Africa, finishing third their first-ever appearance at the event.

Spain's style, which is built on short passes and possession, makes it incredibly difficult for opponents to create scoring chances, let alone get on the scoreboard. Through four matches at the Confederations Cup, Spain has conceded just one goal, compared to three for Brazil.

With Neymar in top form at the moment, Brazil will certainly have its chances this weekend. The only question is whether the hosts will be able to break through against the defensive juggernaut that is Spain.
