Matthew Hoggard has backed England captain Alastair Cook to overcome his current slump in form.
Cook has managed just 145 runs at an average of 24.16 in the first three Ashes Tests, where England retained the urn after establishing a 2-0 lead with two Tests left to play.
Former England bowler Hoggard, who was a member of the side that won the memorable 2005 Ashes series, recalled times when Cook has struggled previously and believes the Essex man will soon return to his best.
Hoggard said: "Cook went through a patch where he didn't know where his off-stump was and he kept on nicking off.
"Everybody was questioning his technique and asking if he should be at the top of the order but Alastair Cook's strength is his mental strength and he's been working really hard with Graham Gooch, who he knows from Essex.
"He's such a solid character he will find a way of getting through this.
"Whether he's having a fantastic innings where everything's easy on the eye or struggling for runs, he has that mental toughness and a will to win."
Rain led to the third Test being drawn, although Australia will have been encouraged by an improved showing, and Hoggard is expecting more of the same from the tourists' pace attack when the fourth Test starts at Chester-le-Street on Friday.
"We always knew Australia were capable of taking 20 wickets and their bowling line-up has held its own all the way through the series, which shows how good their seamers are," said the Leicestershire captain.
"In the times I've played in Durham there is always a bit of seam movement, which will bring back the Aussie bowlers again."
