South Korea coach Guus Hiddink said his team's World Cup quarter-final win over Spain on penalties was unbelievable.
The match culminated in a penalty shoot-out after neither team had been able to breach the opposition's defence through normal and extra time.
South Korea scored all five of their penalties, but Joaquin missed for Spain - and Hiddink's team will now meet Germany for a place in the final.
"I cannot describe how I am feeling right now, but above all I am so happy for the boys," said Hiddink.
"More dreams have come true. We'll have a little glass of
champagne now and what comes tomorrow comes tomorrow.
"The mentality of this team to recover when getting ready to face tougher and tougher opposition is outrageous - it seems to be almost without limits.
"The fans have been fantastic, and all without any violence."
Hiddink felt that there was little to chose between the two teams.
"It was a 50-50 game and the tension was at a super high level. And at the end we took our penalties very well.
"Spain have several experienced players and one or two times in the match they had superiority with their fast counter attacks. But then again we had periods like that as well."
Lee Woon-Jae made a crucial penalty save
Hiddink refused to discuss his team's prospects of beating Germany - but said the World Cup schedule had conspired against his team.
"We approach the next game against the Germans like a bunch
of young dogs, we have nothing to lose.
"We have less recovery time than the Germans - and so the schedule is not working for us."
The Dutch coach also refused to be drawn on whether he will continue with his role after the World Cup.
"My contract expires after the World Cup - and it could have finished by now if we had not got through the group stages.
"I have tried my best to give my knowledge and experience. It has sometimes for the players but they have never given up."
