Australia are being hampered by a lack of natural leaders, according to former national team coach Tim Nielsen.
Australia have made more headlines off the pitch than on it so far during the ICC Champions Trophy, with David Warner having to issue an apology for his bar-room attack on England's Joe Root.
And Nielsen believes the team is lacking senior figures like Ricky Ponting, who captained the Australia side during Nielsen's tenure between 2007 and 2011.
He told Radio 5 Live's Sportsweek programme: "Probably the biggest difference between a lot of great sides is that strength of leadership of your players.
"It doesn't necessarily mean they have to have captain next to their name. They (experienced, senior players) expect behaviour and they understand what is expected of them, just through experience.
Out of line
"If they see young players jumping out of line they quietly and quickly jump in to ensure they straighten them up.
"That's maybe one of the tough things for this side at the moment. They don't have a lot of natural leadership around the group, apart from the actual nominated blokes who have got captain and vice captain written next to their names."
Ponting is currently excelling for Surrey in the LV= County Championship, having retired from international cricket last year.
Nielson reckons he would be able to restore authority to the Test team, but admits he is unlikely to go back on his decision.
"There is no doubt he would help in that regard, having those sort of players around certainly helps," he said.
"It's easy to say from the outside in he would be a good leader of the group and I'm sure he would be, but if his heart's not 100% in it it's probably too much to ask of him as well."
