The Indian cricket team will continue its experiments to figure out the final pieces of a jigsaw puzzle called the 'World Cup squad' as they take on a five-match ODI series against Australia.
The team is slowly moving into the World Cup mode and even a 0-2 loss in the just-concluded T20 series won't see any shift in plans as far as skipper Virat Kohli and coach Ravi Shastri are concerned.
"Every team will look to fine-tune whatever they need to before the World Cup, and we'll keep doing that in the ODI series too, but we still want to win every match we play," skipper Kohli said after the Bengaluru T20 loss headlining his intention.
The Australian team, buoyed by the maiden T20 triumph over India, will be eager to continue the momentum it has gained.
There will be at least four Indian players for whom the series will be like a 'pre-test', a good score ensuring that they get 'admit cards' for the board exams.
The four players in question are KL Rahul, Rishabh Pant, Vijay Shankar and Siddarth Kaul, who are fighting for two available slots in that UK bound 15-member squad.
One man who will be keenly tracking the developments from the sidelines will be Dinesh Karthik, who still, many believe, has an outside chance of making it to the team.
