Needless to say, this will be quite tough for PV Sindhu

PV Sindhu has a heady challenge on her plate as she will have to take on World No. 2 Tai Tzu-ying in the quarters.

Tai Tzu, with her ease of deception, leads 15-5 in the head-to-head and Sindhu will really have to be at her best to overcome the Tai Tzu challenge.
