Buoyant and self-assured in equal measure, India would be eyeing a maiden bilateral ODI series triumph on Australian soil after the path-breaking Test conquest when they take on the home team in the tour finale at Melbourne Friday.
The three-match series is level at 1-1 after Australia won the first ODI in Sydney by 34 runs and India won the second in Adelaide by six wickets.
The Men in Blue have never won a bilateral ODI contest on Australian soil, and their only two series' wins in this format have come in 1985 (World Championship of Cricket) and 2008 (CB Series).
In fact, this is only the second bilateral ODI series India have played in Australia, losing 4-1 in 2016 when they toured here last.
Also, by winning this third ODI in Melbourne, India will finish the current 2018-19 tour without having lost a series here. They have previously drawn the T20I series 1-1, and then went on to record a historic first-ever Test series win here by a 2-1 margin.
While India will take winning momentum into this third ODI, their only worry at the moment is the fifth bowling option.
So far in the series, senior pacers Bhuvneshwar Kumar and Mohammed Shami have been impressive, while the two left-arm spinners Kuldeep Yadav and Ravindra Jadeja have provided control and breakthroughs in the middle overs.
In the absence of Hardik Pandya, India have used a full-time seamer as their fifth bowling option both at the Sydney Cricket Ground and the Adelaide Oval.
Khaleel Ahmed (0-55) and Mohammed Siraj (0-76) though failed to impress in their singular outings.
It becomes a particularly crucial aspect considering that India will go in with the same batting line-up as in the first two matches. With Virat Kohli not keen on bowling Ambati Rayudu again in the series, they need to get their five-bowler attack right on the money.
Seam bowling all-rounder Vijay Shankar and leg spinner Yuzvendra Chahal are in contention and both had a rigorous workout during the optional training session on Thursday at the MCG.
Shankar provides the third seam bowling option, and as an extra batsman, elongates the batting line-up. However, the argument against Shankar is whether the Indian team management can trust him enough to deliver 10 overs on ODI debut.
Siraj struggled to do so and Kohli was left wondering how he would bowl him for a last three-over spell. This is where Chahal might prove to be a more reliable option, even if India have to play two pacers and three spinners.
The bigger boundaries at the MCG, and Chahal's ability to bowl economical and attacking spells as well as use the new ball within the first 10 overs, might be a factor in his favour.
If Kohli does pick Shankar for his ODI debut, it would disturb the set batting line-up and make space for Kedar Jadhav. The fifth bowler's 10 overs can then be divided between Jadhav and Shankar. This move would mean one of Ambati Rayudu or Dinesh Karthik will be left out.
Karthik was handy in finishing the second ODI, while Rayudu has been rusty but seen as India's favoured number four option, making this a tough decision for the Indian captain.
Rayudu was part of the small group that took part in optional training on Thursday, along with Shankar, Chahal, Jadhav, Mahendra Singh Dhoni and Shikhar Dhawan.
Dhoni's form, which has been a constant concern for a while now, has been decent so far and he has two consecutive half-centuries to draw confidence from.
But Australia have named the playing XI for the series decider. They have made two changes, with Adam Zampa and Billy Stanlake coming into the side. Stanlake replaces paceman Jason Behrendorff, who has been ruled out with a back injury, while Nathan Lyon has been dropped to make way for Zampa.
The hosts will be worried about lack of runs from their opening duo, Finch and Alex Carey, with their middle-order having to do the bull work in the last two matches.
Australia have won nine out of the 14 ODIs played against India at the MCG, and it should inspire them on Friday as they are still on the cusp of winning their first ODI series since January 2017.
