I think if the Australian team loses this match so the biggest blame goes to Wade because he is the captain of the team and he didn't select Travis Head for this match. Just another wicket fall and the Australian team isn't able to play Indian bowlers. I think this match winner is India because now Australia's batters have lost their wickets so bowlers are coming to play and bowlers aren't able to do 84 runs in 26 balls.
These matches are just trial and error matches for the upcoming T20 world cup and this T20 Australian squad have only few of the players from ODI WC and I really don't want to stress the players too much for nothing. Even if Australia lose this series they don't lose anything at all in the first place.
