Australia head coach Michael Cheika has claimed that his team selection for this weekend's Pool A clash against England proves that they are ready for the challenge.

The Wallabies have a 100% record in the Rugby World Cup so far having won two of their pool games, while England face elimination should they get beaten at Twickenham on Saturday.

Cheika has made 14 changes to the side that eased to victory over Uruguay last weekend, but it is the same XV that opened the campaign against Fiji.

"I believe that this selection, the same starting team that ran out [against] Fiji, has been really clear on where we must improve and the level we must be at to compete with England and we know that it's going to be a very tough challenge," Cheika told Australian Rugby's official website.

"The group is really committed to making all Australian's truly proud of how we represent them at this Rugby World Cup and Saturday night will be another opportunity for us to do that."

England are currently third in Pool A, behind leaders Australia and second-placed Wales.
