Actually I was confused a bit what I should bowl because I am playing in South Africa for the first time and it was a new experience for me. The wind was good and the ball was drifting so I was confused what to bowl, and which variation to use. So I was asking Mahi bhai (Dhoni) and he told me bowl as you are bowling. It is good that he keeps advising from behind the wickets, it gets easier,
