Even a victory may not be enough for Ian Foster to keep his job when New Zealand lock horns with South Africa once again at Ellis Park on Saturday.

Foster was under massive pressure before the Rugby Championship started and a 26-10 defeat at the hands of the Springboks last weekend ensured the writing would appear to be on the wall for the All Blacks head coach.

That loss in Mbombela pushed New Zealand down to their worst ever world ranking of fifth, and they face another almighty battle against the world champions in Johannesburg.

Australia fought back to start the tournament with a 41-26 victory over Argentina, so the Pumas will be hungry for revenge at Estadio Bicentenario in round two.

SOUTH AFRICA V NEW ZEALAND

FORM

It is now five losses in six Tests for the wounded All Blacks and three defeats in a row. Only once in the past 70 years have they lost more than three games in a row - suffering five consecutive defeats from July to August in 1998.

South Africa have won six of their past seven home games in the Rugby Championship, including four on the bounce. It is the third time they have won four on the spin at home in the competition and they have never managed five straight wins in such fixtures.

The Springboks have won their past two meetings with New Zealand. The last time they won more in succession against the All Blacks was a three-game streak from July to September in 2009.

ONES TO WATCH

The vastly experienced Duane Vermeulen returns at number eight for South Africa after recovering from a knee injury. He replaces Jasper Wiese and will need to hit the ground running.

A standout selection for New Zealand was the inclusion of Richie Mo'unga at fly-half, with Beauden Barrett dropping to the bench a week after he was involved in a nasty collision with Kurt-Lee Arendse. Foster will look to Mo'unga to provide control and set the tempo, provided he gets the ball to enable him to pull the strings.

ARGENTINA V AUSTRALIA

FORM

Australia have lost only one of their past 14 Tests against Argentina, winning 11 and drawing two. The Wallabies have won their last three versus the Pumas; 10 of the wins being decided by margins of at least 10 points.

Argentina are winless in 10 Rugby Championship/Tri Nations game, losing eight and drawing two. They have lost their last seven in the competition and squandered a 19-10 half-time lead last weekend.

It is now five Rugby Championship/Tri Nations victories in a row for Dave Rennie's Australia side, their longest winning run in the competition.

ONES TO WATCH

Former Australia head coach Michael Cheika has turned to Gonzalo Bertranou to start at scrum-half. The pivot must get Argentina ticking and put the Wallabies on the back foot.

Another cruel injury blow for Quade Cooper has opened the door for James O'Connor to start at fly-half for Australia. The number 10 will know he has a great opportunity to put on a show just over a year before the World Cup starts.
