Boosting popularity is key to soccer success

China needs to increase the popularity of soccer if it wants to one day have a world-class team, according to the game's top official in Costa Rica.

Eduardo Li, president of the Costa Rican Football Federation, spearheaded reforms that turned his country into a soccer power.

Costa Rica's team was an underdog that surprised football fans and experts alike by reaching the quarterfinals of the World Cup in Brazil this year.
