It was a tough day in the field for England

Australia have set England the task of achieving the highest-ever run chase but Fletcher feels his side can reach the total and keep the Ashes alive.

"It's an incredible challenge that we have to undertake," he said.

"But at the end of the day sometimes you're there to make some history - the first four batters have got to bat well and see how it goes from there."

Australia took control of the third Test on day three - Adam Gilchrist leading the way with the second fastest Test century - but Fletcher said he was not unhappy with England's performance.

"I thought the bowlers bowled very well in the first two sessions," he said.

"But then you get a guy like Gilchrist who comes out and just takes it away from you.

"The game got difficult for us in that last session when Gilchrist went out and batted magnificently."

Even though England are staring at a third straight Ashes defeat, Fletcher backed captain Andrew Flintoff to rally his side.

"It's difficult at any time captaining an international side in a situation like this," said the England coach.

"It's very difficult for him but he's still up for it. He's still got a smile on his face.

"We realised that at times it could be pretty tough out here and you accept that when you take the job as captain of England."
