Eoin Morgan wary of a galvanised Australian side
The captain also sounded confident about his own fitness.
Morgan was referring to the ball-tampering scandal which left Australian cricket red-faced and which also saw Steve Smith and David Warner banned from cricket for a year.
"What's happened to them in the last six months has the potential to galvanise a young, hungry side," Morgan said at the sidelines of an event in London to mark one year until the start of Cricket World Cup 2019.
"So we're going to have to bring our A game to this series. And again it's going to be a good challenge for us moving forward," he further added.
The skipper also quipped that with the World Cup just a year away, the Australian side will be ready and will put together a strong performance.
Morgan, who pulled out of the ICC World XI vs West Indies match owing to a finger injury, gave an update about the same and said that it is a small fracture in the ring finger of the right hand and that in 10 days, he will be ready to lead England.
The ODI series is slated to start on June 13. Also, Australia will commence their tour with a warm-up fixture against Sussex next Thursday.
