Jason Ryan confident New Zealand will overcome South African challenge

All Blacks assistant coach James Ryan is confident that the All Blacks will be able to match the intensity of the Springboks as the two teams lock horns with each other in the third round of the Rugby Championship at Emirates Airline Park on Saturday.

The Springboks are known for the physicality with scrum and maul will be a challenge for the All Blacks as they look to make a wrong statement against the World Champions.

"We'll have to. We're confident that we've got a game that will suit us," he told the All Blacks' official website.

"We've got some new cattle in there now with the experienced boys that we lost, but we've been impressed with how the boys are buying into our system.

"Our lineout boys have done a great job, especially Toops [Tupou Vaa'i] in the last couple of weeks.

"Toops has done an outstanding job. One of the great things I admire about him is his work during the week, which sets him up to play well. He's a reasonably experienced lock now. He's learnt a lot from Brodie Retallick at the Chiefs. He set them up, as did Sam Whitelock when he was in the All Blacks.

"So, it's great to see those younger boys come in and take their opportunity and play well. He was outstanding in the second Test against Argentina. They were probably his best Test matches in the All Blacks, so the sky's the limit for him."

Ryan also expressed confidence on the availability of Scott Barrett, who missed the first two games against Argentina due to injury.

"What I know about Scooter [Barrett] is the bigger the contest, usually the better he goes. He'll have confidence in his game and getting straight into it."
