England will feel they have the advantage at scrum time, as do most top teams when they play the Wallabies, having smashed Australia in that phase in the past.Remember, the laws have changed. As a result the team that's more technically gifted has a big advantage, so if England have worked even harder with forwards coach Graham Rowntree on how to take advantage of the new laws, then England will profit.
England v Australia this weekend is a tough one to call even though it's being played at Twickenham.
England haven't played at full strength since their 30-3 hammering by Wales in the Six Nations decider at the Millennium Stadium in Cardiff last March and have a lot to improve on.
Australia have won only three of their past 10 matches but are showing signs of improvement under their new head coach Ewen McKenzie.
So which areas will be pivotal to the outcome of Saturday's match, and where might England seek to gain an advantage?
