Stuart Broad instinctively raises his game against Australia - the battle for the Ashes switches him on like nothing else.
He proved the point again in England's 169-run victory in the first test at Cardiff, where he took three of the first four wickets as Australia faltered in their second innings.
It is in the blood for Broad, whose father Chris hit centuries in three consecutive tests on England's successful 1986-87 tour.
He was only months old back then, but soon began hearing what it is like to face Australia - and has since found out for himself in 18 tests that it feels pretty good, especially when England win.
Broad has helped them do so in three series so far and is determined to add a fourth, after the disappointment and embarrassment of a 5-0 defeat Down Under.
