"There is no doubt that it will be a tougher game for the England lads simply because their opponents are an Under 19 squad and a year older," says Fletcher:
"We're also putting together a completely new squad and while our last outing brought a 45-13 victory over South Africa in Kimberley, the group of players on duty at Sale on Sunday will be quite different.
"That said, we have some very gifted players who will not relinquish their unbeaten run of 17 games without a struggle. Australia, in contrast, will remember our last reverse, an 11-3 defeat the last time the teams met in 2007 at Ballymore, and will be keen to repeat that success and get their tour back on track after yesterday's opening defeat at Lymm."
