“I have proven that, even last year, winning back-to-back Madrid and Rome [on clay] ” it was an incredible effort and gives me a lot of confidence and self-belief coming to the clay courts now,” he added.
Djokovic’s comments came after he routed Spanish ace Rafael Nadal 5-7, 6-4, 6-2, 6-7 (5), 7-5 in the longest Australian Open final to clinch his fifth Grand Slam title.
The bookmakers have quoted Djokovic at just 10-1 to win all four Grand Slams in 2012 — an achievement that would be all the more extraordinary given that this is an Olympic year.
Djovokic said he is capable of achieving the rare feat of a clean sweep.
“It is the ultimate challenge to win all four Grand Slams. One player has done it [Rod Laver in 1962 and 1969], so it is possible. Obviously the times are different. Tennis nowadays is much more competitive and much more physical and that makes that challenge more difficult to achieve,” he said.
“But everything is possible. I need to go slowly and really take one tournament at a time but Grand Slams are my biggest priority — including the Olympics” and I will try to aim my form for those tournaments,” he added.
