The fourth and final Test match between India and Australia has gone into Day 5 with all the three results possible at The Gabba, Brisbane.
The call for Steve Smith's reappointment as the Australia captain in Test cricket is gathering momentum with the legendary Ian Healy advocating his return to the top job in the next "12 to 18 months".
India, after conceding a 33-run first innings lead, bowled out Australia for 294, with pacers Mohammed Siraj (5/73) and Shardul Thakur (4/61) doing the bulk of the damage.
The highest successful run chase at the Brisbane venue was in 1951, when Australia finished 236-7 against the West Indies.
With the series locked at 1-1, India need 328 runs for victory or to bat all day for a draw to pull off the remarkable feat of retaining the Border-Gavaskar Trophy despite being severely weakened by injuries and captain Virat Kohli's paternity leave.
They came back and won the Boxing Day Test in Melbourne then batted for more than day to draw Sydney's third Test.
Smith also said that the role of experienced off-spinner Nathan Lyon, will be crucial.
Before the start of play on day four of the ongoing Gabba Test, Bumrah and Ashwin were seen practicing their skills.
But as India have shown since their disastrous capitulation in the first Test in Adelaide when they were bowled out for 36, they are never out of the contest. The start of fifth day's play might get delayed as there is a forecast of rainfall throughout the night today.
"So, tomorrow it is just going to be about bowling (in) good areas and letting the natural variation of the day five wicket sort of do its work and hopefully we can hold on to all the chances", he added.
Rain ultimately ended the day's play early, but not before India, with an inexperienced bowling attack spearheaded by the impressive Siraj, were able to set up a tense final day.
Thakur had earlier picked up the first wicket of the innings when Marcus Harris (38) gloved a catch to wicketkeeper Rishabh Pant in the 25th over.
Smith and Cameron Green then began to take the game away from the visitors, though both had let-offs.
Smith was one of Siraj's victims, out for 55 when he gloved a catch to Rahane after a ball pinged steeply off the wicket.
