The fragile Aussie batting order is the biggest concern for coach Justin Langer heading into his first summer in charge of the Aussie team.
With star batsman Usman Khawaja to see a surgeon back in Australia surrounding his knee injury and uncertain to be fit for the Aussie summer, Warne posted on Twitter on Friday night that opener Aaron Finch is the only batsman who is certain to play in the First Test against India, beginning December 6 in Adelaide.
Warne earlier this week called for selectors to drop out of form brothers Shaun Marsh and Mitch Marsh, suggesting it may be time for selectors to re-call opener Matt Renshaw and allrounder Glenn Maxwell.
He described the manner of Australia's dismissals as "very worrying" and suggested the Marsh brothers, Travis Head and allrounder Marnus Labuschange should all be nervous about keeping their spots in the Aussie team.
He also said destructive batsman D'Arcy Short and returning quicks Josh Hazlewood and Pat Cummins are certain to return to the Aussie test side.
Captain Tim Paine admitted after the loss to Pakistan that his team's batting took a step backwards during the series.
"There's no doubt this has been happening for too long for the Australian cricket team, not just our Test team but probably domestically," Paine said.
"There's a lot of collapses throughout our batting group and I think a lot of it can be technical.
"Some guys will be mental and other guys will be tactical or your plans not being right for certain bowlers. There's no shying away from the fact we have a hell of a lot to do on our batting and it's this team and it's through the whole country."
"It's bitterly disappointing, no doubt. We had some momentum from the first Test, started really well here and then from 5-57 it went a bit pear-shaped to be honest all over the field.
"To come out and do that this Test is like taking one step forward and two steps back. It's really frustrating."
Thankfully the incredible form of Pakistan spearhead Mohammad Abbas diverted some attention away from how much the Aussie top order struggled.
Underrated and seemingly forgotten in Australia's preparations, Abbas had the last laugh when he claimed top honours in Pakistan's Test series victory in the UAE.
Abbas was named man of the series after taking 17 wickets at a remarkable 10.58 with his deceptively dangerous seam bowling.
The medium-pacer crushed any hopes of an Australian fightback in the second Test when he dismissed Travis Head, Mitch Marsh, Aaron Finch and Tim Paine in a stunning day-four spell in which the tourists added just seven runs.
South Africa great Dale Steyn led the praise for Abbas after his 10-wicket haul in Abu Dhabi, suggesting he was on course to become the world's No.1-ranked Test bowler.
Australia went to great lengths to prepare for a Pakistan spin contingent led by Yasir Shah, even flying in a pair of Indian wrist-spinners to face in the nets before the first Test.
But while skipper Tim Paine insisted Australia were ready for Abbas, bowling coach David Saker provided a more illuminating perspective.
"Abbas is so accurate with the ball, and obviously our preparation was more spin-orientated so we've been taken by surprise by the pacer," Saker was quoted as saying by ESPNCricinfo.
A relative newcomer to Pakistan's Test side, Abbas — who has now taken 59 wickets at 15.64 — was the best-performed bowler when Pakistan toured England earlier this year.
"It looks like (Australia) hadn't prepared or that they took him a little easy," Pakistan skipper Sarfraz Ahmed said after the second Test.
"But credit goes to Mohammad Abbas because the pitch is not suitable for fast bowlers. The way he bowled, he was the best bowler on either side."
