Reigning Wimbledon champion Novak Djokovic has been seeded No 1 for the US Open with five-time winner Roger Federer seeded second, the United States Tennis Association announced on Tuesday.

Should both players reach the final of the year's last Grand Slam tournament, they would compete in a mouth-watering rematch of this year's Wimbledon final, a five-set thriller won by Djokovic.

Serbian world No 1 Djokovic has reached the US Open final for the past four years at Flushing Meadows, winning the title in 2011.
