Former India all-rounder Ajit Agarkar believes the challenge for white-ball captain Rohit Sharma is to stay fit and feature in every match coming in future. India's white-ball series against the West Indies, starting with the ODIs in Ahmedabad from February 6, will mark the start of Sharma's stint as the full-time white-ball captain.

"I think it's a good thing and the right thing to do -- to have one captain for white-ball format and now Rohit actually can fly. So, the challenge for Rohit Sharma, in my opinion, is to stay fit and play everything that is there, from now to the World Cup in white-ball cricket.
