The South Korea national football team lost 0-1 to Mexico in the 2026 FIFA World Cup North and Central America group stage. As a result, Korea has 1 win and 1 loss, with 3 points, ranking second in the group behind Mexico. Former coach Klinsmann said on ESPN, 'Mexico had a very good first half.' However, he pointed out that Korea's attacking substitution card was too late. Klinsmann said, 'Korea has players who can harass their opponents at any time. In fact, Korea was fully engaged in the game in the last 30 minutes.' How will coach Hong Myung-bo respond to Klinsmann's assessment? Korea tried to continue the momentum of their comeback win against the Czech Republic, but conceded the first goal due to a critical mistake. In the 50th minute, goalkeeper Kim Seung-gyu collided with Lee Ki-hyuk and dropped the ball, allowing Luis Romo to score. After that, Korea actively used substitution cards, such as calling in Son Heung-min and Lee Jae-sung in the 57th minute, to try to score an equalizer, but was blocked by the opponent's goalkeeper's super save.
