If this is a sign of things to come, I'm afraid Sun Yu can only be near the top but never at the top. Hope she will prove me wrong in future.
Yes. Indeed. She defeated two upcoming Chinese players (Sun Yu is more established though) in their home ground beating one of them in the finals to take China Open title 2016. She has even more potential than this. Her best is yet to come. Gopichand said in an interview when asked about his student, that her best is yet to come. If she brings out those potential, she will be formidable player in the world.
