Mohinder Amarnath says the time has come to remove Mahendra Singh Dhoni from Test captaincy. The former India cricketer says Dhoni's "defensive approach" has resulted in the country's prolonged failure on foreign soil. Amarnath said Dhoni's record is good at home pitches only, like any other Indian captain. The hero of India's 1983 World Cup triumph said that India needed aggressive captains like Mansoor Ali Khan Pataudi to win matches abroad. India had lost successive overseas Test rubbers in England (0-4) in 2011, and Australia also 0-4, in 2011-12. More recently,India lost in South Africa (0-1) and New Zealand (0-1).Dhoni's dismal away record stands at five wins out of 23 Tests, while losing 11 games.Amarnath also lashed out at India coach Duncan Fletcher whose appointment, he thinks, has not yielded desired results.
