Speaking about what was different in this match in comparison to the matches that the team won, the all-rounder said, "The conditions are totally different in Sharjah and Dubai. Bowling and fielding were not good as in the previous match with Bangladesh. Specially bowlers didn't bowl well. They missed and did not bowl in the right areas. Dropped catches also cost us which shifted the momentum away from us. And again the ending was not good. If we had scored the extra 25 runs, the situation would have been different."
