No I don't think they look rattled. I think it's primarily being pushed by the media in Australia because news of Australia winning another one day series just doesn't sell papers, and being pushed in India because of the attention it will receive from the patriotic colonial hating backlash narrow minded crew which litters this board and the country.
They are talking about it because they are being asked about it because it is selling. The Indian media hounded the Australian team for opinions on the Indian players, team, captaincy and T20 win for the purpose of catching one making a frustrated comment. The racism incident has played into their hands.
I don't think it will rattle the Australian's on the field, quite the opposite, they live for this stuff.
