"India's World Cup defence is looking as shaky as Christchurch in the midst of an earthquake. If India are to have any chance of successfully defending the World Cup trophy, they will need the batsmen to score heavily. The bowling has been profligate throughout the Australian tour and there are no signs that failing is about to be rectified," Chappell said.
"In addition, it puts the two best players of the short-pitched ball front and centre, and if it's the intention of opponents to bounce the Indians out, then these two could short-circuit those plans very quickly," he added.
Chappell said that India should replace struggling Shikhar Dhawan by Stuart Binny to open their innings with Rohit Sharma as this will also give them more bowling options.
The former Australian captain said that the Indian bowlers have not learnt anything from the Australian tour so far and also criticised the move to open bowling with Binny in their tri-series match against England in Brisbane.
