'Can't believe it': Shane Warne rages over 'staggering' Nathan Lyon fail

Test legend Shane Warne says he's been left "shocked" by an apparent oversight from Australia, insisting the home side's tactics against India didn't "make any sense whatsoever".

Warne took aim at the Aussies over what he described as negative fielding tactics on the fifth and final day of the decisive fourth Test at the Gabba.

With Australia starting the day needing 10 wickets to win the series and the Indians needing only a draw to retain the Border-Gavaskar Trophy, Warne insisted the Aussie missed a trick on day five - especially with regards to the bowling of off-spinner Nathan Lyon.

A fired-up Warne says he was left stumped by the tactics employed when Lyon was bowling as the Australia spinner chased down the 400 Test wicket milestone.

Stuck on 397 scalps in his 100th Test, Lyon has taken seven wickets for the series entering the final day of the four-Test showdown.

The off-spinner is averaging more than 60 with a strike rate edging towards 140, which is higher than in any previous home Test series.

Lyon was unlucky not to nab the wicket of Cheteshwar Pujara in his first over on Tuesday, with Australia retaining their review of an unsuccessful LBW appeal that had slightly less than half the ball hitting the top of leg stump.

But it was otherwise frustrating viewing for Warne, who couldn't understand why the there wasn't a fielder under Pujara's nose on the off-side.

He said with the security blanket of a Gabba-record run chase of 328 ahead of India that Australia's field settings had been too negative.

"I'm just staggered ... just cannot believe it," Warne said on Fox Sports.

"I'm in shock; it doesn't make any sense whatsoever.

"I don't have an answer, I just cannot explain why he hasn't got one because he knows how it changes his (Pujara's) game, so why on earth would you not have one?

"I'd like to think I know a little bit about spin bowling and I have chatted to Nathan Lyon about it.

"He's admitted it works, but he hasn't got one today."

Plenty of fans found the humorous side of Warne's comments, with the Test legend's persistence about the issue during commentary sparking plenty of response on social media.

Cummins with only breakthrough in 1st session

Warne was also annoyed with Australia's hesitance to change their tactics as Shubman Gill and Pujara, who after the early fall of Rohit Sharma, looked at ease approaching lunch.

"It's not ruthless enough, they didn't try things," he said as Pat Cummins delivered a rare short ball at the body.

"Why haven't they done this earlier; there's that many coaches around the Australian team (that should) say something, it's ridiculous."

The tourists reached 1-83 at lunch on the final day, with Pat Cummins delivering the sole scalp of Rohit Sharma in an impressive opening spell of 1-4 that spanned six overs.

Cummins worked over Pujara during his second spell, landing several body blows plus a knock to the helmet that resulted in a concussion assessment, but couldn't conjure another breakthrough.

The rain radar delivered good news for the hosts at the start of the day after storms hammered Brisbane overnight.

There were fears that wet weather could ruin Tuesday's conclusion to an epic series but play started as scheduled at 9.30am (local time).
