The Serb appointed the six-time Grand Slam winner as his righthand man 12 months ago, since when he has regained the Wimbledon crown and ended the season as world No 1.
Reflecting on his time with the German, Djokovic said: ???I see the partnership that we have going in a positive direction.
???The start of the year was not easy. It took us a little bit of time to get used to our own individual habits and routines, how we work, how we think, how we approach life and how we approach tennis in general.
???He is a legend of the sport, a great champion and former No 1. He contributes a lot mostly from a psychological point of view to my tennis.
???In the last six months of the 2014 season things went the way we wanted and we finished at No 1 in the world. We won many titles so it???s great and I am looking forward to working with him next season.?????
On a more personal note, Djokovic does not expect fatherhood to adversely affect his tennis career.
The seven-time Grand Slam winner said: ???I hope it will not take away the energy from my performances on tour.
???Obviously life is different since I became a father in October but in terms of my approach to the tennis nothing has changed really.
???I am keeping the same team of people, the same routine, the same motivation and of course the same ambitions.??I keep on working hard but now I have more motivation. I have somebody I???m now also playing for.???
And he also had a message of congratulation for Andy Murray, who announced his engagement to Kim Sears last month.
Djokovic, who grew up playing against Murray on the junior circuit, said: ???Andy if you are watching this, good luck.
???It can only be positive of course (for his tennis career). I wish him all the best and I know him and his fianc??e Kim for many years. It???s great to see the relationship he has had for many years is taking the next step.
???We???re expecting them to have children as well so next year we can be one big, big happy family on the ATP Tour.???
