Coach Ravi Shastri vowed that India will "take no prisoners" in their quest to win a Test series in Australia for the first time, but cautioned against underestimating a struggling home team. "I think once you have a sporting culture you will always have that and I always believe no team is weak at home," Shastri said, as he began reparations for the first of three T20 internationals at The Gabba in Brisbane. "We might have three or four players not playing when a team comes to India, but God forbid anyone (who) says it's a weak Indian team because you'll be surprised. So similarly, we are taking no prisoners we want to go out and put our best foot forward and focus on our game rather than what's happening outside." Shastri played down Australia's newfound 'good-guy' attitude on and off the field and simply expects them to play well.
