BRAD HADDIN has fired a sensational verbal shot at struggling India ahead of Friday's third Test in Perth, saying the tourists ''break quicker than anyone in the world'' and turn on each other when events are not going their way.

The Australian wicketkeeper revealed Michael Clarke's team had discussed the mental frailty of Indian players during the hosts' marathon batting performance at the SCG last week in a Test they won by an innings and 68 runs.

While Clarke posted a record-breaking 329 not out, and Ricky Ponting and Michael Hussey compiled centuries, India were made to sweat it out in the field for an eternity, playing into Australia's hands as a 2-0 series lead was established.

''We spoke about a bit of that when we were batting,'' Haddin said. ''The longer we could keep them out on the field the bigger chance we had of breaking them.
