The reigning top football ((soccer)) player in the world, Cristiano Ronaldo, leads his Portugal squad against Germany at the World Cup in Brazil on Monday in an opening-round match between two of the world's top-ranked teams.
The rest of Group G - the United States and Ghana - also face off Monday along with a Group F match between Iran and Nigeria.
Argentina's Lionel Messi, who was player of the year four times in a row before Ronaldo, scored his first World Cup goal since 2006 on Sunday to lead his team to a 2-1 win over Bosnia-Herzegovina.
Also Sunday, France defeated Honduras 3-0 thanks to two goals from Karim Benzema and the first score to be decided using the camera-based goal-line technology.
The most exciting contest Sunday was between Switzerland and Ecuador, who were tied 1-1 as the game went into extra time. Two and a half minutes later, Switzerland's Haris Seferovic took a pass from the left side and directed it past the Ecuador keeper into the top left corner of the net for the winner.
