My heart is in South Africa, through my mum. My mum being from here, me spending a lot of time here as well, I feel most connected to this part of the world.

I was aware of how incredible the match was. Unfortunately there had to be a winner. From my point of view many left feeling sorry for me instead of being happy for Rafa. Which hurts.

I had set a goal with my team to try and get back to the top of the rankings, but I never thought with the depth in the game this year that I would have been able to get it back so quickly.

I am a very positive thinker, and I think that is what helps me the most in difficult moments.

Clearly, when you win everything, it's fun. That doesn't necessarily mean you love the game more.

I did all the right things in so many tournaments. But like I said, sometimes in sports it just goes the other way. Maybe you've already won so much that it evens it out a bit sometimes. I don't know.

I haven't had a cramp since '99. That was my only time, in Davis Cup, when I was panicky. I was young. I'm very proud of that. Never pulled out. Never had cramps. Never lost very much because of fitness, especially later on in my career where I knew I've put in the hard work. I've done that. I've been very fortunate and clever as well to understand how I need to work, when I need to work. So I'm very happy to have stayed injury free for so long. I hope I can still maintain a few good years on the tour. I really hope so.
