Meanwhile, Hiddink, former coach of PSV Eindhoven and Real Madrid as well as the Holland team that reached the World Cup semi-finals in 1998, is just one match from the end of his contract and is expected to return to Europe.
There has been speculation that Eindhoven, where he won the Dutch League three seasons in a row and the European Cup in 1988, want him back.
Hiddink, the first coach to take two teams to the World Cup semi-finals, also played for Eindhoven and he has acknowledged that clubs have been in contact but refused to disclose details until the World Cup is over.
For South Korea, the finals end on Saturday with a match to settle third place against Brazil or Turkey.
