'Apply right pressure'

Skipper AB de Villiers says the West Indies will crumble if South Africa apply the right pressure in their crunch World Cup Pool B game at the Sydney Cricket Ground on Friday.

De Villiers says the Proteas' confidence took a "bit of a slap" in their 130-run mauling by India last Sunday, but they were ready to bounce back against the West Indies.

South Africa cannot afford to lose as they would then have to beat Ireland, Pakistan and the United Arab Emirates to ensure they finish near the top of their pool and secure an advantageous quarterfinal draw.

The West Indies are coming off a spectacular 73-run victory over Zimbabwe with opener Chris Gayle back to his destructive best with the highest ever individual World Cup score of 215 containing a record-equalling 16 sixes, while Marlon Samuels scored an unbeaten 133 in an all-time ODI record stand of 372.

"They're a dangerous cricket team. I believe if you put enough pressure on them like any other cricket team they can crumble," de Villiers told reporters at the SCG on Thursday.

"We haven't played well in the last game so we've got to make sure we look after our side.

"They do have weaknesses in the team and it's important to push those buttons, especially in the pressure situations."

De Villiers, who was run out for 30 at a crucial stage of South Africa's abortive run chase after India's 307, said the Melbourne defeat had not changed anything for them.

"Nothing's changed with our approach except our confidence might have taken a bit of a slap in the last game which is maybe not a bad thing," he said.

"It's maybe a good thing for us to make sure we keep our feet on the ground.

"We've got nowhere to go now. It's only upwards otherwise we're going to stumble out of this tournament."

De Villiers argued against the perception that South Africa were traditionally too tense and uptight in big tournaments and carried a bloated support staff.

"We are in a very good place. It's very easy to say a lot of things about our team after our previous performance," he said.

"Look, I'm also disappointed about what happened there. We only have got the one extra consultant in Michael Hussey. Gary Kirsten has been around the team for a long time as have all the other guys.

"We don't have a psychologist that we normally have in the World Cups.

"I really believe the team is in a good space, we have got the right amount of management here. Every single person knows his role, we didn't do those roles well in the last game and we are hoping to do it better tomorrow."
