England head coach Trevor Bayliss says his side 'must keep out the noise' as they aim to lift the World Cup for the first time.
"We had a chat in the changing room (at Edgbaston) afterwards and realised we have not won anything yet," Bayliss told BBC radio.
"There is going to be a lot of noise around 'you guys are now the favourites', and all this type of thing -- we can't listen to any of that.
"We have just got to concentrate on the way we have gone about our cricket over the past four years and what has got us to this point and go through our process."
After Australia were shot out for 223, Jason Roy struck a blistering 85 off 65 balls to take out the pressure from the run-chase.
Roy was then fined 30 percent of his match fee for showing dissent at the umpire's decision after he was given out caught behind.
Bayliss feels the Surrey batsman will learn from the incident and reach new heights.
"I think it shows the passion Jason has got for the game, and it is such a big game as well, when he was on the verge of scoring a hundred," the England head coach said.
"He will learn from that and go on to bigger and better things, I am sure."
Jason Roy is expected to be picked in the Ashes squad but Bayliss said the focus was currently on squad to face New Zealand on Sunday.
The 56-year-old is set to step down from his role as his contract ends in September.
"I have always been a believer that four or five years is long enough, whether you are doing well or not," he said. "It is time for a new voice for the boys, to hopefully take them to another level."
