Australian wicket-keeper batsman feels India "break quicker than any other team in the world" when things are not going their way.
Haddin's remark comes in the wake of his side's convincing win over a fragile India in the first two Tests of the four-match series.
"We spoke about a bit of that when we were batting. The longer we could keep them out on the field the bigger chance we had of breaking them. We know this side can be as fragile as any team in the world if things aren't going their way and they can turn on each other and the media turns on them pretty quick," said Haddin of the side which had to field for long in Australia's first innings score of 659 for four in the first innings at Sydney.
"We knew if we could keep them out there and put the numbers like we did on the board we knew we would get the rewards because they break quicker than anyone in the world," Haddin was quoted as saying by the Sydney Morning Herald.
Australia have also not let Sachin Tendulkar score his 100th international despite the little master being in good form. Tendulkar has scored 226 runs at an average of 56.5 in the first two Tests, without the elusive century.
Haddin revealed how Australia have been successful in putting Tendulkar under pressure.
"What we have found is if we can build enough pressure on him he wants to score and he wants to feel bat on ball and he wants to get into a rhythm. We find if we can push him a little wider, make him feel for the ball a bit we can build enough pressure to get a chance and it has worked in the last two Tests," said Haddin.
On Tendulkar's much-awaited hundred, Haddin said: "There has been a lot of talk about his hundredth hundred but from our point of view it is our job to make sure he doesn't get it in this series."
The third Test begins here Friday.
