Olympic bronze medallist Saina Nehwal and All England champion Carolina Marin will be fighting it out for the world number one ranking when the Indian Super Series starts next week.
Both shuttlers have the opportunity to attain the top ranking in the sport at the India Open, which starts on Tuesday at the Siri Fort Sports Complex.
Should either of them be successful, it will spell the end of Chinese dominance in the sport and will be the first time since December 2010 that a non-Chinese shuttler was the top-ranked women's player.
Denmark's Tine Baun held the honour in 2010.
Since neither and Indian not a Spaniard has held the rank before, history beckons for both.
Saina is by far the favourite to attain the rank, though. Currently rated number two in the world with 74381 points, she will be catapulted above China's Li Xuerui (79214 points) even if she withdraws from the event.
