In last year's Wimbledon final, Djokovic had replaced Nadal as the world number one. Later, he defeated Nadal again in the US Open decider as he took the season by storm.
Those two victories were among six consecutive wins over Nadal -- all in finals -- during one of the greatest campaigns in tennis history which included the Australian Open, Wimbledon and US Open titles.
The defending champion, who defeated Britain's Andy Murray on Friday, Jan 27 moved into his third straight Grand Slam final. Menawhile, Djokovic is expecting another tough, physical battle against second-seeded Nadal on Sunday.
