Pakistan captain Misbah-ul-Haq is confident his bowlers can cope with South Africa's in-form batsmen at the Cricket World Cup on Saturday.

South Africa are the first team in history to belt consecutive scores of 400, as they thrashed both West Indies and Ireland in Pool B.

They face Pakistan in Auckland on Saturday, but Misbah is hopeful his team's bowling line-up have what it takes to contain the likes of AB de Villiers, Hashim Amla and Faf du Plessis.

"I think our bowling has been really doing well. We are confident that we've got bowlers who can really get a wicket against any team. So let's see," he said on Friday.

"I mean, in the past even we have played against South Africa, these guys played against South Africa in 2013 and 2014 quite a lot, and they know how these batsmen play, and their performances are really good.

"We are confident that we've got a bowling attack that can really put them under pressure."

Pakistan's biggest problem at the tournament has been losing early wickets, including slumping to 1-4 and 4-2.

Asked if his team were taking the wrong approach at the top of the order, Misbah said the loss of wickets were the biggest worry.

"Actually we have been just losing wickets at the top. That's why we have to really pull ourselves back," he said.

"But we also just we are also looking at our strengths. We know that we've got a bowling attack where if we cross 250, no team in the world is just, you could say, relaxing chasing that 250.

"We have our targets, and we play according to our strengths, and the kind of start we had in the last game, if we can really repeat it against the top sides, we could really manage to score 300.

"It's all how you start the game and then how you finish the game, so it's really important for us to have good starts, then to really just go and score big."
