South Korean national football teams coach Choi Kang-hee has stepped down following the 1-0 defeat at home to Iran during a qualifying match for the 2014 FIFA World Cup in Brazil.
On Wednesday, Korea Football Association (KFA) confirmed Choi's exit, and began the search for a replacement to lead the squad in next years tournament.
The KFA has decided to accept Chois wish to resign at the end of his contract after having completed the teams qualification for Brazil in 2014. We thank him for his efforts and wish him well," Korea Football Association said in a statement.
Choi came on board in December 2011. Hong Myung-bo, who coached South Korea's Olympic team to a bronze medal at the 2012 London Games, is one of the "strongest candidates" to replace Choi.
Huh Jung-moo, vice president of the KFA, told a news conference that they would hold discussions and make a formal announcement about a new coach early next week.
Local media said Argentine Marcelo Bielsa, who left Athletic Bilbao earlier this month, and Turkish coach Senol Gunes, who managed Korean team FC Seoul between 2007 and 2009, are possible foreign coaches being considered.
On Tuesday, Iran secured its place at the FIFA 2014 World Cup after it registered a 1-0 victory against South Korea at Ulsan World Cup Stadium.
The 2014 tournament in Brazil will mark Irans fourth World Cup appearance.
Iran went to the FIFA World Cup in 1978, 1998, and 2006.
