It takes a lot to shout at /scare /intimidate a much younger player (opponent),and at the same time more talented, like the way Saina could. I really do not know anybody of this nature in the entire international badminton circuit.
46:20 and 47:00 very bad behaviour by Saina. Though I am from India, Can't expect this from any player. Shouting on junior like this just depicts lack of proper behaviour and sportsmanship. Today Tai TY is at top, Saina is nothing infront of her today!
