unforgettable tour of India, with two defeats in two Tests back to back taking away the chance of reclaiming the Border-Gavaskar Trophy and leaving them to correct a lot of mistakes, as pointed out by former skipper Michael Clarke.India hammered the Aussies by an innings and 132 runs in Nagpur and followed it up with a six-wicket win in Delhi to take an unassailable 2-0 lead in the four-match series. Clarke feels the biggest mistake Australia made was not playing a tour game ahead of the four-Test series that began February 9.Instead, Pat Cummins chose to simulate Indian conditions back home before having a short camp near Bengaluru ahead of the series opener in Nagpur.
