25-year-old Djokovic, who had played best tennis from the beginning of the 2012 season, where he has finished as No. 1 in the ATP Rankings for the second consecutive time this year. Serbian said he had failed to repeat dream 2011 season, but played good tennis to win Australian Open and appeared in the final at French Open and US Open.
Five-time Grand Slam champion Djokovic has dethroned his rival World No. 2 Roger Federer to grab No. 1 in the ATP Rankings by end of the season, as he thrashed Swiss legend to lift the 2012 ATP World Tour Championship Finals this month in London. Serbian will have to face big challenge against Federer from the start of the season for top spot, while Andy Murray is one of the top prospects in the race.
