Talking about ex-India captain MS Dhoni being criticised by ex-players for his batting, Team India head coach Ravi Shastri said, "Nobody is good enough to criticise MS Dhoni." "If you talk about him, do you even know anything about cricket?" he added. "Dhoni is like Sachin, Kapil and Gavaskar. These guys come once in 30-40 years," he further said.
