Virat Kohli is expected to have a key role when India takes on England in a high-voltage five-match Test series at the Rajiv Gandhi International Stadium in Hyderabad on January 25.35-year-old Kohli, who has scored 29 centuries and 30 half-centuries, is expected to become a big threat for the opposition team. Kohli has been in good form of late after becoming India's leading run-scorer and second-highest run-scorer overall in the two-match Test series against South Africa.
