India play Australia in five Tests starting Friday in Perth after their first red-ball series defeat at home in more than a decade exposed the visitors' growing vulnerabilities.

Virat Kohli has been struggling for form of late, but the veteran Australia spinner has nothing but respect for the Indian, who he says is a champion you can not write off.

Ahead of the India-Australia Test series starting on November 22, former Indian cricketer Sanjay Manjrekar shared his insights on Virat Kohli.

Coming into the Border-Gavaskar Trophy on the back of a whitewash by New Zealand at home, Ravi Shastri feels the only way India can match Australia Down Under this time is if they bring out their A game immediately.

This year, he has averaged only 22.72 across six Tests, and in the three games against New Zealand, he could manage only 93 runs.

Former Indian captain Sunil Gavaskar believes Virat Kohli's hunger for runs, coupled with his impressive track record in Australia, will be crucial as he aims to overcome his recent struggles. Kohli's performance will be closely watched as Australia prepares to test him with targeted strategies aimed at exploiting any perceived weaknesses.
