It's funny! sometimes captains says they take inspiration from series which was played 3 years back and if they happen to loose a game the same guy will say history doesnt matter, every game is new game and we have defeat in our last game back of our mind. Last time when india fought to Aus: (i) Pitches werent made too fast, they werent typical pichtes one get in Aus (ii) India had 2 in form openers. Chopra was very resolute not to loose his wicket no matter what. I doubt we have it this time arround. (iii) Indian middle order is same but 3 years older now, so though they are experienced they have lost flexibility in terms of fitness (iv) Everything Sehwag did clicked, Luck doesnt favour team/person all the time.
I think Aus are too formidable side to beat and India will have to do something special to beat them. I think India will loose comprahensively.
