David Warner has clearly looked out of touch but his opening partner Usman Khawaja believes that mere three innings is not big enough sample size to judge the Aussie veteran. India pacer Mohammed Shami has already dismissed Warner twice in the series with fuller length angled-in deliveries and questions over the 36-year-old's technique have been raised.Khawaja, who made an impressive 81 on the opening day of the second Test defended his opening partner saying that he is very confident of Warner's capabilities of bouncing back.“I have to kind of disagree with what you're saying. He hit two fours of Ashwin in the last game before he got out lbw so he was showing some aggression,” Khawaja said, when asked if Warner, whose stay looked painstaking during the 44 deliveries faced, needs to be pro-active.
