Ben Youngs spoke as
England made their final preparations to face Australia in their first
World Cup knockout game since 2011. Youngs played in that campaign in
New Zealand, in which England lost to
France at the quarter-final stage, and he said his team would have to make a quick start to avoid being shocked by the intensity of the game.
Australia beat England 33-13 in their last World Cup meeting in 2015, but England have won all six games that the sides have played since then.
