Huh wary of Uruguay threat

South Korea coach Huh Jung-moo admits he is concerned that last-16 opponents Uruguay have yet to concede a goal at the World Cup.

The Koreans could name an unchanged line-up for Saturday's match at Nelson Mandela Bay Stadium in Port Elizabeth, with Cha Du-ri set to continue his role at right-back after featuring against Nigeria.

Diego Godin is a doubt for Uruguay after missing the 1-0 win over Mexico through injury, so Mauricio Victorino is ready to fill in again if the Villarreal defender is ruled out.

Huh fears his side may struggle to break down Oscar Tabarez's men, who have kept three clean sheets in as many games.

"Uruguay have been very good in their defence, but although we may have let other teams score goals, we have also scored goals as well," he said.

"We have let in lots of goals, but we can make up for that by scoring twice every time we lose a goal.

"We are doing our best to work on that."

Uruguay coach Tabarez has hailed his side following their progression to the last 16 but insists they are far from finished yet.

"Of course we've analysed all the possibilities for us," he said. "I think so far in this phase we've showed that we are a tough team to tackle for the others. We are trying to do what we had exactly in mind before the tournament. Now I don't think we've achieved that yet, but Uruguay is now a difficult opponent for anybody.

"This is what we have seen so far and if you look at the history of Uruguay in the last few World Cups, this win is really satisfying and the news from Montevideo is very good."
