South Korea suffer more warm-up woe
Beaten 4-2 by Zambia at the weekend, the Koreans again fell flat against the Platinum Stars in Rustenburg on Wednesday.
A frustrated Huh criticised his players but also blamed the fast-flying official "Jabulani" World Cup ball for his side's inability to find the net.
"I sent 20 (outfield) players on the field today," Huh told Thursday's Korea Times after changing his entire outfield line-up after the first half. "We did not give an impressive performance.
"We are still trying to get used to the new ... ball. We couldn't finish because we aren't used to the ball."
Midfielder Kim Jung-woo added: "I had trouble kicking (the ball) properly let alone effectively controlling it."
South Korea, semi-finalists as co-hosts in 2002, have been in South Africa for a week to acclimatise to the altitude.
They have been drawn alongside Argentina, Nigeria and Greece in Group B at this year's World Cup. Huh's side head to Spain for friendlies against Finland and Latvia later this month.
