Coach Huh Jung-moo has confirmed Park Ji-sung is back to full fitness and ready for South Korea's World Cup opener against Greece on Saturday.

The Manchester United midfielder sat out the Taeguk Warriors' final warm-up match against Spain with a minor thigh injury but has returned to training without experiencing any further problems.

"Park Ji-sung is fine. He felt a slight soreness on his hamstring so we didn't let him play in the friendly against Spain so as not to aggravate it," Huh said in the Korean Times.
