Andrew Flintoff says England now believe they can win the Ashes after a thrilling win in the second Test.
With the five-match series tied at 1-1 and the third Test at Old Trafford starting on Thursday, Flintoff insisted: "We think we can win it."
But he expects a tough fight, adding: "We're going to have to play well - they're going to come back hard.
"I'll enjoy this result but on Monday morning I'll be back working on my game and getting ready for Thursday."
Flintoff starred with two half-centuries and seven wickets at Edgbaston to win the man-of-the-match award.
But he has not yet enjoyed the same success in two Tests at Old Trafford, where he plays his county cricket for Lancashire.
"It's not the best of hunting grounds for me but they're familiar surroundings and I know everyone," he said.
"I've got my own space in the dressing room and all my mates are there. I can't wait to play and Ashes Test on my home ground."
Head of selectors David Graveney told BBC Radio Five Live, England would stick with the same XI for Manchester.
He was not concerned about Flintoff's shoulder-problem, which needed a pain-killing injection on Saturday.
Graveney said: "As far as his shoulder is concerned he is going to be OK. He didn't have any trouble lifting up a can of beer anyway."
Flintoff paid tribute to the efforts of Australia's lower order batsmen, in particular Brett Lee, after they almost managed to force an upset victory.
"We came out expecting to win but I don't think anyone expected it to be quite like that," he said.
"We kept fighting and we knew it would only take one ball, we just didn't think it would come down to that.
"Brett Lee was outstanding. I tried to bowl him out, tried to knock him out, everything. He was unbelievable."
Number 10 batsman Lee battled on despite being struck painful blows to the elbow and left hand by Flintoff.
He finished 43 not out, having shared stands of 45 with Shane Warne and a further 59 with Michael Kasprowicz.
"He bowled outstandingly well yesterday and batted his heart out today," Flintoff said of Lee.
"I went over to him at the end and congratulated him, and said 'You have got to be proud of what you have done there'."
