Boss Shin Tae-yong has said that he still feels "a little bit empty" despite watching South Korea defeat Germany at the World Cup.
Last-gasp goals from Kim Young-gwon and Son Heung-min earned South Korea a famous 2-0 win in Kazan, while defending champions Germany were eliminated from the competition.
However, South Korea have also missed out on a place in the knockout stages, and while acknowledging the magnitude of his side's victory, Shin has admitted that it is tinged with disappointment.
Shin is quoted by FIFA's official website as saying: "I feel great but at the same time I feel a little bit empty, so I feel a little bit ambivalent.
"Yesterday we said there was only a 1% chance and so I told my players it really was a last-ditch effort for them and I told them that they had to fight until the end.
"Germany are the defending champions and number one in the FIFA Ranking, so I thought about what mistakes Germany might make, because they probably felt they would be able to beat us – that's what everybody thought. I thought we could use that as a reverse strategy and that has really hit the nail on the head."
South Korea finish in third place in Group F, with Germany ending the opening stage in bottom spot.
