Langer said he was wary of an Indian side led by the incomparable Virat Kohli, that is aiming to win their first Test series ever in Australia. The series is even more important for captain Kohli as it would also define his legacy as a leader having already established himself as world's premier batsman.
The mercury is forecast to soar to 39C on Thursday for the beginning of the four-Test series, heightening the significance of Tim Paine and Virat Kohli's pre-match coin toss.
It looks like a squad on predicted lines apart from the inclusion of Rohit Sharma, who had not played a Test since January in South Africa.
Based on recent Tests at Adelaide Oval, which have been played on a lush pitch designed with one eye on protecting the pink ball, Australia believe they do not need an extra bowler.
With four Tests in a month, some of them on unforgiving tracks, the value of Marsh's bowling should increase through the series. But, for many, a win in the series could be his legacy as a captain.
"If they bowl, just keep the pressure on and Josh Hazlewood in particular, to me, is a key part of that".
A question mark remains over whether Peter Handscomb or Travis Head will fill the vacant middle-order spot.

But the Indian skipper is insisting he has grown up and will not be looking for confrontations, although he added that "if they want to play a certain way we will reciprocate".
But veteran opener Murali Vijay, who was dropped following a pair in the second Test against England this year, rose to the challenge with a century in the same match and is expected to face the new ball with KL Rahul.
"This being the first Test we think they will do the job at hand".
"They haven't had great success in Australia in the past, as Australia haven't had in India".
They will then have to pick three pacers which in all likelihood would be Mohammed Shami, Jasprit Bumrah and Ishant Sharma and the lone spinner Ravichandran Ashwin.
"He's shown that over the last few years, he bowled a mountain of overs in the UAE and our quicks are fresh so we can cover that".
So the tossup is between Hanuma Vihari and Rohit Sharma.
