Paine wants long-term progress

Australia captain Tim Paine insisted Wednesday that his priority was to develop his inexperienced cricket team for the future even as they face the prospect of losing a home series against India for the first time.

But he pledged that Australia would still pick the "best XI that we think is the best combination to win this Test" once they had seen the Sydney pitch.

Australia, who have never lost a home series against India, go into Thursday's fourth Test 2-1 down and in danger of Virat Kohli's men completing a historic landmark Down Under.

While Australia must win to level the series, Paine said that his aim was on improvement, particularly in the batting department, with home Tests to come against Sri Lanka ahead of an Ashes tour to England this year.

"It doesn't for me personally," he said on whether preventing an India series win was his key motivation.

"Other guys may use it but my focus has been on us improving and on us playing the best possible cricket that we can and when we haven't, making sure we learn from it."

The hosts' top order has largely failed to fire and the odds are mounting that the underperforming Aaron Finch will either be pushed down or axed, with number three Usman Khawaja moving up to open alongside Marcus Harris.

"If that's the way we go, Usman will go out and give his all as he always does. I think the way he's handled the last month or so has been exemplary, it's a real credit to him," said Paine.
