MELBOURNE - Novak Djokovic set his sights on completing the elusive career Grand Slam at this year’s French Open after confirming his mastery of men’s tennis at the Australian Open.With six Grand Slam titles at the age of 25, the Serbian world No 1 could be forgiven for taking it easy but immediately after clinching his fourth Melbourne win, his mind was on Roland Garros in May.Djokovic has gone from the Paris quarterfinals to the semifinals and the title match in successive seasons, falling to seven-time winner Rafael Nadal last year, and now he wants to take the last step."I want to go all the way in the French Open. I went to the finals last year and had a great match against Rafa, but he’s always the favourite on that surface and he’s the ultimate player to beat on clay,” Djokovic said."But I think if I continue on playing well, stay healthy, I can have a chance.”It all seemed routine for Djokovic as he beat Andy Murray in four sets, picked up the trophy and US$2.5 million winner’s cheque, and then headed straight to the airport, eschewing parties and the usual day-after media commitments.Australian Open victories in 2011 and 2012 proved a springboard for Djokovic, who put together 145 wins against just 18 losses over the two seasons and finished both years as the world No 1.With Nadal’s physical state unknown, following his long break with knee problems, victory in Paris does not look a long shot for Djokovic, who would surely then target the hallowed calendar-year Grand Slam.Djokovic received the trophy from Andre Agassi, another four-time Australian winner who managed to lift all four Grand Slam titles during his career.
