Australia's opener Chris Rogers believes there are signs that the Old Trafford wicket could deteriorate later in the match to help the tourists fight their way back into the Test series.
Rogers made 84 on the opening day of the third Test in Manchester where the Aussies struck more 300 runs under a hot sun.
With England already leading two-nil in the five-match Ashes series, Rogers fully understands the importance of Australia's successful start to the third match.
Australia reached 303-3 by stumps and Rogers said: "We've put ourselves in a good position and Friday is another important day and if we can keep going and the wicket breaks up for us then we can put England under a little bit of pressure.
"We've copped a lot of criticism so far but that has made us fight and today that helped us.
"But we need to keep going on Friday. This is as good as the wicket will get to bat on, so we must take advantage.
"We must keep batting and there are some cracks in it so we must put pressure on England for the first time in the series."
As for facing Jimmy Anderson, who failed to take a wicket on Thursday, Rogers added: "You have to concentrate hard. He can swing the ball both ways and you mustn't lose focus.
"You've got to watch it as hard as you can and hit it as late as you can."
In the end Rogers fell 16 runs short of what would have been a maiden Test ton, trapped leg before by Graeme Swann.
He added: "The ball was there to hit through square leg but I missed it. That's it."
