Australia captain Aaron Finch on Thursday declared that he will return to his "natural" aggressive game in the series-deciding third ODI against India after being left "frustrated" by a cautious approach while searching for runs.     

Finch has been going through a bad patch for a long time and the sword is literally hanging over his head.

After a below-par showing in the Test series, Finch's struggle with the bat continued in the ODIs as he scored just 12 runs in the first two games.

"I am little bit frustrated. I am trying to bat a little bit longer for one thing. When you are searching for runs, you can be searching for the right recipe, and over the last couple of days, I have had a look at footage. I have seen things that have worked out when I got a hundred for Australia last, and what didn't," Finch said ahead of Friday's final ODI.

"I want to give myself the best chance. Maybe, I have been too tentative in the last couple games and letting pressure build up."

Finch, who scored just 97 runs in six innings in the Test series against India before being dropped for the final game, has admitted that he has spent the last few days in reminding himself he is "still a very good player".

"That's always a fine balance between attack and hanging in there, waiting for the right time to be aggressive and take on the opposition. I still feel I am a very good player," he said.

"I think 13 international hundreds suggest I do know what is required. It is about seeing through the initial part and putting pressure back on the bowlers. It is just about going back to my natural game, letting it flow and finding the right rhythm."

With the series evenly poised at 1-1, Finch said Australia is keen to come out victorious on Friday to register their first ODI series triumph since January 2017.                          

"We are very keen to win the series. It has been a while since we have won one," he said.

"Coming up against a real powerful Indian line-up, there have been some positives particularly with the bat and there has been a lot of improvement in the last 8-10 months to be really proud of in the two games. It's 1-1 also because our bowlers have been outstanding.

"A lot of improvement can be made but a lot to be proud of in this series as well. Winning the series is our main focus," he signed off.
