Novak Djokovic was asked if he has a comfort zone on his mind. The Serb said: "I do not think there is such a thing as the stagnation or comfort zone. If everything is evolving and moving, so is our lives within, so it's just hard to just have a safe place and say, I'll stick to this and that's it.
I also feel like we are pushed by new generations. We have to improve on the tennis court. I do have frequent conversations with my coaches about my game in general, about one of the things that make me feel good or that can be improved.
And then it changes, depending on the year, depending on the surface and it's exciting because there is always something to work on." Alexander Zverev said: ""It has been a rough year on the court and especially off.
I am just generally happy to be back, to sort of give myself a chance to retain the title. I have those memories from last year so happy to be back and the last part of the year has been exciting. The confidence was not there at all, so many double faults.
It was not tennis. I did not forget how to play tennis but how to hit a serve. Some things were influencing mentally outside the court. I have been playing through that. Team8 helped me a lot with it and happy to be back. I had a rough year but at the end of the year I am top of it and I am one of the best players this year.
Everybody is saying my season was bad but I am number seven in the world so it's not that bad. I want to improve on a lof of things. I am definitely excited."
