"He's as ready to go as he possibly can be. I'm sure he's going to play a huge part in this series."
Australia's bowling coach Craig McDermott believes Johnson has tapered his preparations perfectly for the Ashes following a relatively quiet recent series against the West Indies.
"Jonno's arm path has got a bit better over here, a bit higher and he's got his seam in a better position, and he's just got a real spring in his step at the minute."
Meanwhile, Jimmy Anderson only has good memories of the 2009 Ashes opener.
England's last-wicket pair of Anderson and Monty Panesar batted for 40 minutes and 69 balls to hold on for a draw in Cardiff.
"I remember there was very little expectation on myself and Monty and we just tried to do as best we could by wasting time and using all the tactics we could to escape," he said. England went on to win the series 2-1.
"It was a painful test match," Brad Haddin said of the first test held at Sophia Gardens. "We thought we got ourselves into a position that we deserved that win, but as you see in Ashes campaigns - they're never over. It's different cricket and it brings out a lot of different emotions, and some odd batting talent that I didn't think Monty Panesar had."
Shane Watson suggested the gutting defeat sapped his side's momentum leading into the second test in London, where England had their first Lord's victory over Australia since 1934.

Three key contests
Mitchell Johnson v Adam Lyth and Alastair Cook
Jonathan Trott was to open this series but his retirement made way for Lyth. The 27-year-old made a century in his second test, while Cook also scored runs against NZ. Can they see more of the new ball or will Johnson wreak more havoc?
Ben Stokes v Shane Watson or Mitch Marsh
The value of a game-breaking allrounder who can turn a test with bat or ball was well highlighted by Andrew Flintoff's heroics in the 2005 series. The combative Stokes will draw confidence from the fact his maiden test ton came in Perth, while Watson and Marsh are locked in a selection battle.
Nathan Lyon v potentially seven left-handers
Lyon has already stated he can't wait to attack the hosts' mollydookers. The offspinner has improved significantly since the 2013 series and looms as a point of difference. The hosts are expected to back allrounder Moeen Ali to perform their spin duties instead of using a frontline tweaker.
