The 21-year-old Serb is currently third in the ATP rankings just 10 points behind Federer in second after a superb 2008 season.
Victory at the Australian Open was followed by semi-final berths at Roland Garros and the US Open.
And despite getting knocked out in the second round at Wimbledon Djokovic feels he can overtake the world's top two this season.
Djokovic said: "Being number one in the ATP rankings is always my goal and I think it's reachable.
"I have enough quality to get there, but I must be careful not to forget my priorities in trying to achieve that goal.
"I have to concentrate on all those little things that one needs to do to reach the goal.
"I'm a perfectionist and always want to do better. I have room for improvement, and that's good.
"I have high ambitions, and I want to continue with good results and games, especially in major tournaments."
