Captain Agustin Creevy insists Argentina will not shy away from a revenge mission against Australia at Twickenham on Saturday.

The Pumas skipper has challenged his side to secure a second Rugby Championship victory this weekend, to avenge their World Cup semi-final defeat to the Wallabies at the same ground.

Former Worcester hooker Creevy also admitted Argentina already have one eye on their world ranking ahead of May's pool draw for World Cup 2019.

Argentina are determined to force themselves inside the world's top eight by the end of the autumn fixtures, to ease their potential fixture run at the next World Cup, in Japan.

"We want revenge not only for the World Cup, but also for our defeat to Australia two weeks ago in Perth," said Creevy.

"Revenge is definitely in the mind, and we're not afraid of that."

"We want to put things right from those two games. It's very important for us to win on Saturday.

"Losing here at Twickenham against Australia at the World Cup really hurt a lot.

"So revenge is definitely in the mind, and we're not afraid of that.

"But the most important thing really is to win the game, to meet our pre-tournament objective of two wins in the Rugby Championship.

"And then also there are the world rankings too, for the World Cup draw.

"We know in November we will have our last chances to improve our rankings for the World Cup.

"If we can get a win this weekend that would hopefully put us in a good position with the rankings."

Saturday's match will create history as the first Rugby Championship clash staged in the northern hemisphere.

Pumas skipper Creevy believes Argentina will be "totally comfortable" at Twickenham, playing one of their home matches on foreign soil.

"We feel totally comfortable, as if we were on home soil," said Creevy.

"Twickenham is the best stadium in the world, and we want to put on a good show, and we hope the English crowd will enjoy that.

"We accept where we have to play, we enjoy playing here.

"Of course we like to play at home in front of all our crowd, but this time we're playing here and we're very happy to do it.

"Even though they have suffered many changes since the World Cup we still consider Australia one of the strongest teams in the world.

"They know how to play against us, so we respect them and we consider it to be a really hard game."
