I enjoyed the position I was in as a tennis player. I was to blame when I lost. I was to blame when I won. And I really like that, because I played soccer a lot too, and I couldn't stand it when I had to blame it on the goalkeeper.

You know, I don't only play for the record books.

I definitely need to use my chances when they come because definitely there wont be many.

No, I'm not (disappointed). There's no reason to be because I'm on an incredible run. You always expect a loss once in a while. So when it happens, why be disappointed if I win over 90% of my matches.

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 never expected i, in the first place, when I started playing tennis, that I would ever carry the flag into the Olympic Stadium for an Olympic Games... So for me that was a surprise and a huge honor in my life to be able to represent Switzerland.

I have a very strong opinion. I'm absolutely against it. I'm against the challenge system. I'm for the way it is right now. Don't change that.
