Mahendra Singh Dhoni will return as India captain in the five-match ODI series against New Zealand starting in Dharamsala on October 16. Dhoni last played an international match - a T20 - against the West Indies in Lauderhill, USA in August 2016. Sunil Gavaskar told NDTV in an exclusive chat that it will be challenging for the 35-year-old Dhoni to hit top form. Gavaskar feels Virat Kohli and the bowlers will be key to India's chances against a good ODI side like the Kiwis.
