What a day for Indian badminton!

We now have three quarter-finalists in the 2017 World Championships - Saina Nehwal, PV Sindhu and Srikanth Kidambi.

You can find out how Sindhu won her match here.

You can find out how Srikanth won his match here.

Saina Nehwal next faces the winner of the third round contest between the sixth seed He Bingjiao and the 16th seed Kirsty Gilmour.

Saina made the World No. 3 Sung look clueless and reduced to a pedestrian player in the last few points like only Saina can!

Every time she was down, she turned it around with confidence!

That's why Saina is Saina!

She joins PV Sindhu and Srikanth Kidambi in the last-eight.

Saina is into the QUARTER-FINALS OF THE WORLD CHAMPIONSHIPS!!!!!!
