India will need to improve their batting in the ongoing Test series against Australia, if they are to script a comeback from their loss in the opening match, former India captain Sunil Gavaskar told NDTV on Monday. "If you get dismissed in two innings in about (a total of) 75 overs, it doesn't speaking very highly of your batting. It doesn't speak very highly of your determination or your application. It doesn't speak very highly of your temperament. And I think that's the area they need to look at," he said.
