Shane Warne believes Mitchell Johnson will "shake up" England's batsmen with his fearsome pace when the Ashes gets under way next week.
The left-arm speedster has been recalled for the series opener in Brisbane after impressing in the one-day internationals against England and India.
Johnson was overlooked for last summer's Ashes as he continued to struggle with his control, but Australia legend Warne has backed him to get his lines right this winter.
"He's forced his way in through bowling some serious pace. He's going to shake the English side up," Warne said.
"He's a bit older, a bit more mature and knows his role a bit better, knows his body better, knows how he bowls. His role's going to be go out to just bowl quick."
Warne also backed the decision to hand batsman George Bailey his Test debut at the Gabba after he averaged over 90 in the recent one-day series in India.
"If a guy's in form it's pretty hard to resist," Warne added. "He's been consistent in making those runs and the way he's been getting them."
The former leg-spinner conceded that Australia were outplayed during the summer, but he feels they have a great chance of reclaiming the urn on home soil.
"The squad all look happy, they're all in form, so all the signs have been good for Australia," he said.
"England were the better side in England in the last Ashes series. They deserve to be favourites for this series. But we're on Australia's turf. It's time for our guys to put their hand up."
