Shane Warne believes Australia's bid to win the second Ashes cricket test in Adelaide is Ricky Ponting's greatest challenge as captain.
Writing in the London Daily Telegraph, Warne says the task of getting Australia to regroup and focus will be a tremendous challenge for Ponting, after the humiliating conclusion to the drawn first match in Brisbane.
Warne also thinks Ponting needs to be less flighty as a leader, having made too many changes in his efforts to get wickets in Brisbane.
The second test starts on Friday.
