Touring side crushed by the Three Lions with the sides preparing for final game.
In what has already been a long battle for the Australian Test cricket side, they have lost plenty of ground to the English side.
Not only have they lost the chance to retain the Ashes, but they have also missed out on the chance of saving face from the English tour by coming away from the five-game series level at 2-2.
Australia crumbled late on day four at Chester-le-Street as England brought about a stunning batting collapse as the away side went behind 3-0 in the series.
However, with the final clash of the series less than a week away, starting next Wednesday at The Oval, David Warner beleives his side cannot dwell too much on the past.
