Ashton Agar says that Australia are keen to exploit any uncertainties in the England camp following their defeat to Scotland.
England suffered a six-run loss in Edinburgh with Calum MacLeod scoring 140 not out. Jonny Bairstow hit a century for England but it was in a losing cause.
It was good for us that England lost that game because you always like to start things off with a win.Ashton Agar
It was not the way England would have wanted to go into a five-match ODI series against Australia.
The tourists beat Middlesex by 101 runs in their final warm-up for the series which begins at the Oval on Wednesday and Agar hopes they are high on confidence with England rather lower.
He said, ahead of Wednesday's game: "I think we've got momentum coming into these tours and to play a couple of practice games and get a couple of wins is great for us.
"It was a really interesting game yesterday. It was good for us that England lost that game because you always like to start things off with a win.
"It was great for Scotland as a country and as a cricketing nation. It is very exciting for them, you could see how excited they were. It was a good game to watch."
However Agar added that England, despite the defeat, were the number one ranked 50-over side for a reason and were always dangerous opponents.
England recently drew the two-Test series against Pakistan but now have to wait until August for the series against India with white ball cricket dominating for the next few weeks.
The series against Australia concludes with a T20 international between the sides which is followed by England taking on India in three more T20 games and then three ODI's before the five-Test series.
England are 1/66 to win the series against Australia who are 11/1.
Agar is 7/2 to be Australia's best bowler in the series while Bairstow is 7/2 to be England's top batsman.
