Seven captured a heated discussion on the field between veteran paceman Sharma and star spinner Jadeja, who has been limited to drinks duty and substitute fielding in Perth.

Jadeja was controversially left out of the tourists' XI for the second Test despite Ravichandran Ashwin's injury, with the tourists opting for a four-prong pace attack.

It's unclear what Jadeja and Sharma were arguing about but it wasn't a friendly discussion.

The pair went chest to chest before two teammates, including Mohammed Shami, eventually helped restore order.

"It does seem pretty animated," Ricky Ponting said on Seven.

"There's lots of finger pointing. They were separated on a couple of occasions."

Meanwhile, Shami believes his side erred by not picking a frontline spinner as they hunted an unassailable 2-0 series lead in Perth.

Ashwin's absence has been made all the more glaring by the form of Nathan Lyon, who captured the prized scalp of Virat Kohli on day four at Optus Stadium.

In sharp contrast, offspinning allrounder Hanuma Vihari failed to take a single wicket in Australia's second innings.

Shami, who claimed career-best figures of 6-56 on Monday, opted against toeing the party line when asked about the absence of a tweaker in the XI.

"I feel there should have been a spinner, but these things depend on your management," Shami told reporters in Hindi.

"The team management makes these decisions. We can't do anything about it.

"We had one spinner (Vihari) who didn't bowl badly."

Lyon, the series' leading wicket-taker, admitted on Sunday he was surprised India didn't pick a spinner.

Shami, who inflicted the painful blow to Aaron Finch's right glove that prompted the opener to retire hurt on day three, consistently extracted good bounce from the demonic pitch in Perth.

The right-armer, who has taken 11 wickets at 18.8 in the series, believes India's pacemen are much better placed to trouble Australia on this tour compared to his previous visit in 2014-15

"We have an Indian pace attack where all the bowlers are fast and are bowling good lines and lengths," he said.

"Four years ago we weren't this experienced. Now we have the experience. You must have seen the difference in our accuracy ... (compared to) four years ago."
