The round of 16 is traditionally when a World Cup sparks into life, and it could be a cracker when Uruguay take on South Korea in Port Elizabeth on Saturday.

Both sides are confident after performing well in the Group Stages, but after taking seven points in Group A, it is no surprise to hear that Uruguay boss Oscar Tabarez is full of belief that his side can do well.

The South Americans would have topped their Group even if they had drawn against Mexico, but Luis Suarez's header secured a deserved victory as a side built on a solid defence - Uruguay are yet to concede a goal in the tournament - continued to impress.

And with Suarez and Diego Forlan posing a danger to any opponent, it is no surprise that Uruguay are being tipped for a semi-final berth, as they would face either the USA or Ghana if they beat South Korea.

"I think so far in this phase we've showed that we are a tough team to tackle for the others," said Tabarez.

"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."

Yet South Korea should not be underestimated. The 2002 semi-finalists came through a tough group that included Argentina, Nigeria and Greece, scoring five goals in the process.

Their principal threat is likely to come from Park Ji-Sung, Park Chu-Young and Lee Chung-Yong, all of whom have scored in the tournament.

Before the Finals, coach  Huh Jong-Moo said his aim was to reach the knockout stages, and now that has been achieved they are setting their sights higher.

"Our goal was the last 16, so now we just focus on every single game coming up and treat it as the Final," Manchester United star and South Korean skipper Park Ji-Sung told The Daily Yomiuri.

"We watched a few of Uruguay's games, they have quality and they are strong and their performances were great in the group stages. We have to prepare well for that game.

"We're just thinking about the next game, we don't want to think about the game after that."
