That is a little bit hard to understand because at the end of the day, this is our team. And by all means, criticize after but not before. Because by criticizing anybody before, any player, you are actually demoralizing that player."Gavaskar continued:"Once the series is over, you can by all means ask why he was picked because then you also have the benefit of hindsight. But once the team is selected, we should all absolutely 100% back the team and want it to win. Because at the end of the day, it is our team, it is India's team."Following Rana's brilliant spell, the Indian batters made light work of the target, completing the run chase in the 39th over with nine wickets in hand.Harshit Rana finishes as the leading wicket-taker in the Australia-India ODI seriesHarshit Rana silenced all his critics by finishing as the leading wicket-taker in the ODI series against Australia.
