The stand-in Indian cricket captain Virendar Sehwag rates the current Australian pace attack as among the best he has faced in his 10-year test career.
Australia's quicks - Ben Hilfenhaus, Peter Siddle, Ryan Harris, James Pattinson and Mitchell Starc - helped skittle India out twice in tests in Melbourne, Sydney and Perth to take an unassailable 3-nil lead in the series with three crushing wins.
With the fourth and final test starting in Adelaide today many are questioning whether the hosts dominance is a case of the home side bowling well or India batting badly.
Sehwag says the current crop of Australian fast bowlers are the best in the world.
The veteran batsman will lead the tourists in Adelaide after regular skipper MS Dhoni was suspended for a slow over-rate.
The fourth test gets underway at 1pm.
