"I obviously always expect a lot from myself, but it's a fact that I'm not playing close to my best, and I know that,” he said. "Again, I'm trying, as everyone else, to work on the game and, you know, work on things. Sometimes it works, sometimes it doesn't."
Djokovic, who won the 2016 French Open to get his fourth Grand Slam victory in a row, now holds none of the four majors. Having fallen to No. 2 in the rankings, he will be No. 3 or No. 4 following the tournament. But he insists he is fully motivated to get back to the top.
"You know, it's one of the highest points that you can reach as a tennis player, is to be No. 1,” he said. “And, of course, one of the highest goals of any player. You know, I was very fortunate, obviously, to spend a lot of time there. It’s more about the game itself—my own game, you know—working on it, because obviously there are things that need to be better and I need that continuity.
"I'm going to focus on that, and then I guess results will follow, and No. 1 ranking, as well. Then I will have a better chance if I start playing better.''
But at the moment, he isn't sure what to do. The 30-year-old also recently stopped working with his coaching team, and has added Andre Agassi as a part-time coach. He is also looking for another full-time coach.
