Watson, who is featuring in the team only as a batsman these days, said their side is determined to do well after suffering a heavy defeat in the series-opener in Chennai.
"We need to win this Test match. We need to be certainly at our absolute best to beat India. They played very well in the first Test. Ashwin bowled beautifully in those conditions and M S Dhoni batted unbelievably well to take the game away from our reach. So we have to be certainly at our absolute best," Watson said after team's practice session here.
Watson did not reveal if Australia will play an extra spinner in the second Test match, beginning Saturday.
"I think that is something selectors are weighing at the moment. No doubt that India's game plan in Chennai was significantly different from ours as we saw in the second innings when their quick bowlers hardly had four or five overs which is a big contrast to what our team did. Option are going to be there. We have a game plan and have a team which can succeed," he said.
