Springbok captain expects all-out assault from All Blacks

South Africa captain Siya Kolisi expects an all-out assault from the All Blacks when the two sides meet in their Rugby Championship test in Pretoria.

After a surprise away win in New Zealand last month, Kolisi is awaiting a backlash in the last match for both teams in this year's southern hemisphere competition.

"Obviously the All Blacks have already won the Rugby Championship, but we have heard them speaking of the fact that they are coming here with a real desire to win this one," Kolisi said.

South Africa's 36-34 win in Wellington was only the fourth time the New Zealanders have lost since they won the 2015 World Cup.

"We can all see that this is a game that is very important to them and where they will be looking to get their revenge. We're aware of what to expect and how physical it will be."

For South Africa to pull off a rare back-to-back triumph over the All Blacks, Kolisi said they would need to replicate the successful ingredients of the last meeting between the two rugby superpowers.

"The most important thing is to have the same intensity of Wellington, or even greater," he said. "Our focus for that game was really just to produce the best performance we possibly could without worrying too much about the score.

"We know they are going to take it up a notch, they've made that clear. From the word go, we must be ready, and ensure that our all-round game is on point," the Boks captain added.
