South Korea president Lee Jae Myung is calling for an investigation into the country’s poor World Cup showing and ensuing resignation of coach Hong Myung-bo. South Korea did not advance out of Group A while earning three points in three matches. South Korea beat the Czech Republic and lost to Mexico and South Africa. Lee said he was “utterly baffled” by the showing and questioned why Hong was selected as coach. Hong, a former star defender for the country, said Sunday that he was stepping down.
