Having brushed aside some of the biggest names in the sport already,... Korea's up-and-coming tennis star Chung Hyeon faces the biggest moment of his life today: an Australian Open semi-final against the man widely considered to be the greatest player in history: Roger Federer.
The 21 year-old Korean is ranked 58th in the world and Federer is currently world number two.
Federer has a staggering 19 Grand Slam titles under his belt,... including five Australian Open titles.
The match comes as Korea is in the grips of the "Chung Hyeon fever" with the nation seeing a huge jump in sales of tennis goods.
The semi-final will start at 5:30PM, Korea time, on Friday.
The winner will play Croatian Marin Cilic (chee-leech) in Sunday's final.
