"That's why I kissed the court. I've had a love affair with Rod Laver Arena for many years and I hope it can last a long time."

(On winning his 11th Grand Slam)

"It's phenomenal. I'm very proud of it, as is my team. We worked very hard to be in this position, and we should enjoy it. We should cherish every moment that we get to experience now, because these are the tournaments that we all value, that we all want to play well on. No doubt that I'm playing the best tennis of my life in last 15 months. You know, everything is going well privately, as well. I became a father and husband, have a family, so I feel like I'm at the point in my life where everything is working in harmony. I'll try to keep it that way."

SOUNDBITE: (English) Novak Djokovic, Australian Open champion:

(On if he feels he has separated himself from the rest of the big four having beaten Rafael Nadal, Roger Federer and Andy Murray convincingly already this year)

"I don't want to allow myself to be in that frame of mind. Because if I do, the person becomes too arrogant and thinks that he's a higher being or better than everybody else. You can get a big slap from karma very soon. I don't want that."

(On his form)

"I'm not here because I played the same tennis I played last year. I feel like I'm playing better. I always strive to improve not just the game or technically, tactically, but also mentally."
