Rafael Nadal insists his appetite has not been sated by completing a career Grand Slam with victory at the U.S. Open last month, and intends to prove it at this week's Japan Open.
World No. 1 Nadal beat Novak Djokovic at Flushing Meadows to finally capture the one major title that had eluded him throughout his illustrious career, making him the youngest player to win all four majors in the Open era.
But the 24-year-old Spaniard on Monday brushed off suggestions that he would be content to bask in the glory for the rest of the season, setting his sights on victory in Tokyo over the coming week.
