The reigning world champions in One-Day International (ODI) cricket, England, would start as favourites, when Eoin Morgan-led side lock horns with Australia in the first ODI of three-match series at The Old Trafford, Manchester on Friday. England will be boosted by the return of explosive batsman Jason Roy, who was ruled out of T20I series due to injury. Joe Denly, who was originally named in the ODI squad as a reserve, has left the bio-bubble, while T20I star Dawid Malan, who is at the top of the ICC T20 batsmen rankings, has been named as a reserve.
