World No. 1 Novak Djokovic believes he is in the prime of his career after winning Indian Wells last week, where he defeated Roger Federer for his fourth career title in the desert.

The Serbian has now won 50 tournaments, passing his coach, Boris Becker, who won 49. The eight-time Grand Slam champion has been ranked No. 1 since July 7.

"I am at the prime of my career," Djokovic. "I'm going to try to use every part of this fact to stay where I am and to fight for as many major titles as possible. I know that my career, as any other career, cannot go forever. I cannot stay in the top for, so many years. I'm going to try to have longevity in my career through every day, let's say, routines that I respect with my team, with preparations, recoveries, and of course consistently motivating myself, finding that inspiration to play the sport in a high level."   
Roger Federer, Rafael Nadal, and Djokovic all spent time at No. 1 since the Swiss took the spot for the first time on February 2, 2004. Nadal made the ascent on August 18, 2008 and Djokovic took over on July 4, 2011.     
"I know that all this success that I make are not result of one tournament or a couple weeks of work," Djokovic said. "They are result of many years, putting in these hours of practice and commitment. So that's the only way I can stay here. That's the only way I can have many more years on this level."
