Australia confirmed their XI on Thursday, with four changes from the side that won in Sydney. Clarke, Haddin and Warner will all miss after being rested, while Xavier Doherty will also be left out on a surface expected to offer more to the fast men. Bailey will return from injury and Johnson from a rest, while the other two inclusions are Steven Smith for his first ODI in more than a year and Matthew Wade, who is keen to prove that he still has plenty to offer at international level.
Australia 1 Aaron Finch, 2 Shaun Marsh, 3 George Bailey (capt), 4 Steven Smith, 5 Glenn Maxwell, 6 Matthew Wade (wk), 7 Daniel Christian, 8 James Faulkner, 9 Mitchell Johnson, 10 Nathan Coulter-Nile, 11 James Pattinson.
The promotion of Ben Stokes to No.3 in the Sydney match did not work out for England but Perth was the site of his maiden Test century during the Ashes, so they may be inclined to give him another chance. James Tredwell might struggle to hold his place given the expected pace in the WACA pitch, although Boyd Rankin is unavailable due to a hamstring problem, so Chris Woakes could come in if Tredwell is left out.
England (possible) 1 Alastair Cook (capt), 2 Ian Bell, 3 Ben Stokes, 4 Gary Ballance, 5 Eoin Morgan, 6 Ravi Bopara, 7 Jos Buttler (wk), 8 Tim Bresnan, 9 Stuart Broad, 10 Chris Jordan, 11 James Tredwell / Chris Woakes.
