VIDEO: Rugby World Cup 2015 - England set for must-win Australia clash

After last Saturday's agonising defeat to Wales at Twickenham, host nation England's hopes in the 2015 Rugby World Cup are hanging by a thread.

Up next for Stuart Lancaster's men are Australia. They face the Aussies in a must-win game on Saturday.

Beat the Wallabies and England are all but guaranteed their place in the next round. However, a draw would still earn the men in white a stay of execution. 

Defeat and it's goodnight England.
