South Africa coach Hugo Broos has huge respect for their final group opponents South Africa at the World Cup on Wednesday.
"They run 90 minutes. It's like they have been plugged before the game and you take out the plug and they start running. And this for 90 minutes," Broos said in a national federation video.
"It's a difficult team," he said, urging his side to match the intensity in their must-win match.
Mexico have won Group A with six points, South Korea have three points and South Africa and the Czech Republic one each.
Broos will be without key midfielder Teboho Mokoena who converted a late penalty in a 1-1 draw against the Czechs but has to serve a yellow card suspension on Wednesday.
“We have to be honest, this is a loss for the team. He plays a key role in shaping the way we play. He’s a leader on the pitch," Broos said.
