What happened at the World Cup?

South Korea opened Group A with a 2-1 win over the Czech Republic but then lost 1-0 to Mexico and 1-0 to South Africa, finishing third and failing to qualify for the round of 32 as one of the eight best third-placed teams.

The expanded 48-team tournament had raised expectations that South Korea would reach the knockout stage, with local media labelling the squad a “golden generation” headlined by former Tottenham Hotspur forward Son Heung-min, Paris St Germain midfielder Lee Kang-in, and Bayern Munich defender Kim Min-jae.
