Saina vs Yihan... My prediction is 35 - 65 %.. Yihan has psychological advantage when it comes to play against saina.. Though Saina changed her coach to correct her movements and strokes, she has certain areas of weakness which was correctly pointed out by the male commentator of her match against Kim Hyo min. Yihan with world class coaches besides her, they might have pointed out already . Let's see how it goes.. I will be happy if she takes atleast one game..
