The Rugby Championship resumes tomorrow after a two week break, and we head into it with each side looking for a hugely significant victory.

New Zealand travel to Argentina, where a win will all but guarantee them the title. With Dan Carter back in the starting team and Aaron Cruden moving down to the bench, the All Blacks are now looking even more potent.

They will not underestimate the Argentinians though, who have been strong throughout the tournament and in their only other home game secured a deserved 16-16 draw with South Africa.

Argentina are desperate to get a victory is their first year in the competition, and none would have more significance than beating the almighty All Blacks.

It is at fly half where we are likely to be treated to the greatest spectacle, with the undisputed world number 1, Dan Carter, facing the outrageously gifted Juan Martin Hernandez. For anyone wanting a lesson in how to play the game, it would be well worth keeping an eye on those two.

It is at fly half in the other game that all eyes will be fixed on too. Australia travel to South Africa having removed Quade Cooper from the squad after his twitter outburst, moving the woefully out of form Kurtley Beale to fly half, with Berrick Barnes moving to full back.

It seems a rather odd decision given that Barnes has been the form player in the Aussie backline, and has spent more time at 10 than Beale. Most observers would say you don’t want to move an out of form player to the key pivot position, but Robbie Deans is a man under pressure, and he knows that Beale has the magic within him, and is capable of doing the outrageous to win games.

South Africa have their own fly half issues, after dropping Morne Steyn. Steyn has been kicking poorly, and when your role in the team is to guide them around with your boot, that is not a good sign.

Heyenke Meyer has picked in his place the 20-year-old Cheetahs fly half, Johan Goosen, who makes his first Test start.

Neither side can really afford to lose, with both having come under a lot of criticism for their performances in the competition so far. The Springboks have not lost against the Wallabies at Loftus Versfeld for 49 years though, and will be determined not to let that proud record slip.
