South Korea U23

Under manager Hong Myung-bo, the South Korean under-23 team participated at the 2012 Summer Olympics in London. In the group stage, South Korea qualified for the quarter-finals as runners-up of their group by beating Switzerland 2–1 and drawing with Mexico and Gabon in two goalless matches. In the quarter-finals, South Korea met hosts Great Britain. South Korean forward Ji Dong-won scored the opening goal, but British midfielder Aaron Ramsey scored a penalty equaliser. Ramsey once again had a penalty chance four minutes after his penalty goal, but South Korea's over-aged goalkeeper Jung Sung-ryong blocked it. However, Jung was injured in a collision with Micah Richards in the middle of the second half, and was replaced by Lee Bum-young. Nevertheless, Lee did not concede a goal until the end of extra time, and made a save from the shot of Britain's fifth kicker Daniel Sturridge in the penalty shoot-out. South Korea beat Great Britain 5–4 on penalties and Lee was praised by finishing the game successfully, but the compliments turned to criticisms after the semi-finals. He conceded three goals against Brazil, failing to perform his role. After being eliminated by a 3–0 loss to Brazil, South Korea competed with their historical rival Japan for a bronze medal. Their over-aged striker Park Chu-young scored the opening goal with a solo effort against three Japanese defenders, and Koo Ja-cheol scored an additional goal, a decisive one for the victory. South Korea won their first-ever medal in Olympic football after defeating Japan 2–0, and the medalists were exempted from mandatory military service according to the laws of the country. They were called the "London Generation" in South Korea, and most of them played for the senior team in the 2014 FIFA World Cup in Brazil, where they were eliminated after finishing last in their group.
