Improper coaching and over confidence..... I think Aussies well-observed and mastered over usual and the same old techniques and performance of Indian players and may be, they found weak and negative sides of Indian team., Indian team has to still learn more techniques from them and do more practices.

Australia's top notch swing bowling, and collapse of our batsmen! We've always been poor travelers out side Sub continent and this time it is much worse because teams have understood the lack of skills to play proper swing bowling. Also australia has done very good analysis and dried up all scoring possibilities and with the kind of hostile bowing, batsmen are bound to fail.
