Sounders FC v Atlético de Madrid (June 19, 3 p.m. PT) Africa - 4 CAF teams. Europe - 12 UEFA teams. North and Central America, Caribbean - 4 Concacaf teams.

More than 30,000 fans showed up for Seattle's Club World Cup opener on Sunday. But Sounders fans weren't all pleased about the dynamic pricing for the tournament.

Despite FIFA's lofty ambitions, the Club World Cup has so far played out in front of half-empty stadiums, the result of steep ticket prices, poor promotion and a misread of the U.S. market.

It’s taken time for the Club World Cup to build brand awareness, but opening weekend drew huge crowds in Miami, NYC and Los Angeles.
