Australia's pack will not be embarrassed by England in Saturday's World Cup showdown at Twickenham, according to Michael Lynagh.
Aussie Lynagh - a World Cup winner in 1991 against England at Twickenham - and now a Sky Sports expert, says the Wallabies' secret weapon is their Argentinian coach, Mario Ledesma, who has been improving their pack.
It's a huge game for both teams. But for England, defeat will almost certainly end their chances of reaching the quarter-finals.
England's eight have regularly splintered the Aussie scrum in recent years, giant prop Andrew Sheridan famously destroying them in the 2007 World Cup in France.
The England pack was far superior in their last meeting back in November at Twickenham too. But Lynagh says hiring Ledesma - the great Pumas hooker - has worked wonders.
"They suffered at the hands of the English pack last November. But the Australians have improved markedly since then," he said.
"Mario Ledesma has come in and worked with the pack for about a year. Our props are in form. We've got good locks. There is an opportunity to atone for last November. The Australians know that they are going to be attacked in the scrum - and they will be ready for that.
"The squad, and in particular the starting 15, has been pretty settled for a while now. That squad played against Fiji and did OK. So they are settled, going into what is a huge game. This is probably Australia's biggest game at Twickenham since the World Cup final in 1991.
"Australia, this time last year, were in a bit of disarray and a lot of problems. They have improved a lot. Michael Cheika has changed the team and they seem happy. Contrast that to England. They are still a bit unsettled. That loss to Wales last week would have hit them pretty hard.
"For England, at least they only had to wait seven days for another chance, to turn that around.
"That's a big issue for Australia - confronting England, who are hurt from last week, at home. It's sudden death rugby for England.
"The support last week at Twickenham was amazing. I've not seen a crowd like that - it was incredible. The English crowd for their team... they know it's a last-ditch effort...
"It will be a great shame for the tournament if the hosts go out."
