"I agreed to maintain our relation," said Hiddink. "We'll see what we can do after two years."
"I don't want to make an end to that relation," added the 55-year-old Hiddink of his ties to South Korea. "It's too precious for me."
"There's a process going on right now in Korean football that is very interesting," he said of his young squad.
The Dutchman also confirmed hat he was to talk to Eindhoven about the vacant coaching job, but that nothing was settled yet.
"I will have my conversation next week with Eindhoven," he said.
PSV Eindhoven is the club that gave Hiddink his start as an assistant coach in 1983.
He had played there and went on to become head coach, leading them to the Dutch League championship three times and to the European Cup in 1988.
Hiddink coached at Fenerbahce in Turkey and Spain's Valencia before taking over the Dutch national team in 1995.
After the 1998 World Cup he then coached in Spain at Real Madrid and Real Betis before taking the South Korea job in December 2000.
