Wallabies coach Ewen McKenzie feels that Australia has a better chance of winning on Saturday against Argentina.

The Australians are desperate to clinch a victory which could reinvigorate and boost the team's morale.

McKenzie will make the necessary tweaks to match up against the Pumas who have shown flashes of brilliance despite not winning a single game in the 2013 Rugby Championship.

"We made it clear before our first game against New Zealand that this group had very strong ideas around how they wanted to approach and play each game," McKenzie told abc.net.au.

"Australian rugby is renowned for smart, attractive and running rugby and there is a continued determination from the coaching staff and players to play with ambition and flair. We aren't moving away from this philosophy."

Meanwhile, the All Blacks feels that the match against South Africa on Saturday is what they have been waiting for, as they latter is the only team that is capable of giving them a good fight.

"These games can be [crucial] particularly when one team takes a lot away from it. You can build real momentum towards a World Cup that's a few years away," All Blacks Centre Conrad Smith told allblacks.com.

"We're certainly viewing it as the biggest challenge since the World Cup so we're prepared for a big game and I know they will be as well."

While knowing that their team is a force to be reckoned with, Smith remains levelheaded and acknowledges the fact that the Springboks has been on-form in the past months.

"We always respect whoever we're playing but it didn't take much to look at that Springbok performance last week, and in the weeks previous, to know they're playing some pretty good footy,"

"And if we're not on the mark then we're going to come second.

"That strikes a bit of fear and hopefully it brings out the best in us."

"When they're really playing expansively and chancing their arm a bit that we know we're in for a real battle,"

"You know you're always going to get physicality with the Springboks but when they're really well with the ball in hand they pose a real threat."
