Why is it that the opposition got 200 and we couldn't even get 120? Why are their bowlers getting more spin?"' 'These are questions that we never get asked throughout the year, right? Because the coaches who are there know what's going on. You are only answerable to the coaches and the selectors, who have all played cricket and understand the nuances of the game.'
For the first time in many years, India are going into a home Test match as underdogs and not favourites. Ask any player worth his salt and he would tell that it is not a happy place to be.
