Cricket legend Sunil Gavaskar on Friday advised rest for Indian skipper Virat Kohli and said that he should come out to bat only 'if needed'. "I don't think Virat should bat at No.4. He should come out to bat only if needed. Rahane (Ajinkya) can come at No.4, Nair (Karun) at No.5 and then Saha at 7," Gavaskar said in an exclusive chat with NDTV. Gavaskar also asserted that India will have to bat really well to get close to the Australia total and a lot will depend on Cheteshwar Pujara and Murali Vijay on how they bat on Day 3.
