Coming into the Test against Argentina on Saturday, Pumas assistant coach Graham Henry cautioned Ewen McKenzie's Wallabies to avoid employing "chessboard rugby."

In spite of losing five of their last six Tests, Henry still feels that Australia has the upper hand in their fixture at the Patersons Stadium.

Boasting a World Cup under his belt with New Zealand in 2011, Henry stated that the Wallabies needed to explore more options in their game plan for them to get back to the apex of Test rugby.

''[The Wallabies] are struggling, aren't they. The Wallabies were the best team in the world at the turn of the century. It will come again it's just a matter of when,'' Henry told the Sydney Morning Herald.

''A couple of wins under Ewen will put that right ... they'll gain some confidence."

''When they were the best team in the world, they played an expansive game ... it will happen again. Rugby is a simple game. It doesn't take a couple of years to build a team, it can take a week. Hopefully not this week."

''[Attacking] is the way they should play in my opinion. That's their mentality and skill level, you're not going to win by playing chessboard rugby, kicking in the air and chasing it."

''That's not the way Australians play. I think they're trying to play the right way.''

The Pumas has not defeated Australia since 1997 and are looking to further improve their tactical nous by acquiring Henry.

The Wallabies's confidence shattered when they lost the series against the British and Irish Lions.

Henry thinks that regaining the lost confidence is vital to build on their form.

''They're still recovering from that and struggling a bit."

"I thought [Genia] was the best halfback in the world a year ago. He's not playing as well as he has and I'm not sure why, but he's an outstanding rugby player.''
