South Korea's players were just a bunch of no-hopers one month ago - but not anymore.

Although the football world may still find their names unfamiliar, they have certainly become well known in Italy, Spain and Portugal.

Ahn Jung-hwan, Park Ji-sung and Seol Ki-hyeon are just three of the men Germany will have to look out for if they are to avoid the fate of their fellow European big guns.

AHN JUNG-HWAN

The golden boy of Korean football scored the golden goal against Italy, prompting his Serie A club Perugia to tell him he was no longer welcome.

He rose high above Italy captain Paolo Maldini to nod home the winner and add to his headed goal against the United States.

The attacking midfielder is difficult to mark, drifting late into the box in much the same way as Michael Ballack does for Germany.

Liverpool's Dietmar Hamann is likely to be handed the task of halting Ahn's forward runs, should both pass late fitness tests.

SEOL KI-HYEON

Like Ahn, Seol put disappointing club form behind him to prove his worth to coach Guus Hiddink.

And the Dutchman's faith was rewarded when the Anderlecht striker hit the late equaliser against Italy.

A powerful and mobile target man, he typifies a super-fit Korean side.

However it is likely to be his pace rather than his strength that will trouble the German defence.

PARK JI-SUNG

Park is another player who only won his place in the Korean side late in the day.

But once there, he has proved to be the innovative and creative force that Hiddink had predicted.

Useful from free-kicks, the 21-year-old showed the skill that will worry the Germans when he scored the winner against Portugal.

Park coolly controlled the ball on his chest before smashing it into the net.
