South Korea coach Huh Jung-moo has promised an attacking display in Tuesday's crucial Group B showdown with Nigeria as his side look to secure just a second appearance in the last 16 of a World Cup finals.

South Korea began their campaign with an impressive 2-0 win over Greece but lost 4-1 to a rampant Argentina on Thursday and currently sit second in Group B alongside Greece, who came from behind to beat 10-man Nigeria 2-1 to record a first victory at a World Cup finals.

Huh's side currently hold the advantage over Greece by virtue of goals scored and South Korea know victory over pointless Nigeria would secure a place in the last 16 for the first time on foreign soil, as long as Greece fail to beat Argentina.

"Our players aren't disappointed or discouraged from the loss to Argentina," said Huh.

"We will prepare thoroughly as our third match against Nigeria will be the final showdown in the group stage."

Wins for both South Korea and Greece on Tuesday would leave the pair level on points with Argentina, meaning qualification would be decided on goal difference.

"We won't go out on the field aiming for a tie," added Huh. "It will be a difficult match but we will play a winning game."

Nigeria, who also lost 1-0 to Argentina, will be without the suspended Sani Kaita, who was sent-off against Greece after kicking defender Vasileios Torosidis with the Africans leading 1-0.

"As seen in the case of Sani Kaita who was sent off the field, we need to put pressure on the Nigerians so that they become agitated and lose their temper," added Huh. "We cannot allow them to play freely on the field."
