India captain Mahendra Singh Dhoni expressed his happiness after Australia's 4-0 whitewash in the Border-Gavaskar Trophy, which the home side retained on Sunday with a commanding win.

"You have to answer what's right and what's wrong," Dhoni said at the post-match press conference after India's 4-0 victory over Australia.

"When four fast bowlers play, it's strategy and when three or four spinners play, it becomes a bad wicket! When a deep point, deep fine leg and deep third man is kept for Virender Sehwag, it's a strategy but if MS Dhoni uses a deep point or deep square leg for David Warner, it's a defensive field set," said a sarcastic Dhoni.

PTI reported that the Indian captain was categorical in stating that the era of playing "aggressive cricket" is gone.
