Hong Myung-bo has resigned as head coach of South Korea following the team's elimination in the group stage of the World Cup.
He announced his decision at the team's training camp in Guadalajara after the squad failed to qualify as one of the best third-placed teams.
"I would like to sincerely apologise to the citizens who have loved Korean football and always supported the national team," Hong said. "The responsibility lies entirely with me."
Hong was appointed in July 2024 to replace Juergen Klinsmann and led the country to its 11th consecutive World Cup appearance.
The Korean squad, featuring stars Son Heung-min, Lee Kang-in and Kim Min-jae, was expected to advance from a group with co-hosts Mexico, Czech Republic and South Africa.
The team opened with a 2-1 win over the Czech Republic but suffered subsequent losses to Mexico and South Africa, sealing their early departure.
