Jason Gillespie believes Australia can upset England in the Ashes

Former Australia international Jason Gillespie has said the Baggy Greens can cause an upset in next summer's Ashes series.

England have won three of the last four series since 2005, including a 3-1 win in Australia in 2010-11 and recently completed their first series victory in India since 1985.

Gillespie is confident Australia can impress when they face England later this year.

"I think Australia versus England in Ashes cricket is the ultimate in Test cricket, it's as simple as that," Gillespie told Sky Sports News.

"I don't necessarily agree England have the edge over Australia with conditions. I think a lot of people over here are going to be surprised just how good a pace battery Australia have created.

"There are a lot of young fast bowlers, who all bowl close to 90mph, all getting opportunities playing international cricket. That will hold them in good stead for the next couple of years."

The first 2013 Ashes Test takes place at Trent Bridge on July 10.
