Australian vice-captain Michael Clarke is in no doubt about what is required for his team to beat England if they are to retain the Ashes.
Speaking ahead of the third Test in Edgbaston which begins on Thursday, Clarke told a press conference that Australia would have to be at their best to win.
"We need to be playing our best cricket to beat England in these conditions," he said.
He also revealed that no firm decisions on the team line-up have been made as yet, noting that all members of the touring squad have been told to prepare as if they are playing and he also believes that spin will be a part of the match in Birmingham.
"Spin will play a part, depending on the weather," he forecast.
He also paid tribute to the retiring Andrew Flintoff, joking that he will "not be too disappointed" not to be facing him in Test cricket after the series.
Australia trail England 1-0 after a draw in Cardiff and a 115-run defeat at Lord's.
