I've done so many interviews over the years in so many different languages. Radios. Papers. Magazines. There's always another interview to do. It's quite something, I have to say.

When they [court announcers] say, 'This is the world No. 2,' it just doesn't sound right to me because either I'm No. 1 or I'm a grand slam champion. I'm not world No. 2. I just don't like the ring of it when I'm introduced on court because I've been up there for so, so long.

My family is the thing I miss most on the tour.

I have to fit holidays around tournaments, particularly the grand slams, in Melbourne, Paris, London and New York.

When you're good at something, make that everything

When I think of the Olympics I only think of good things. I think of what a great event it is and what it has done for me and my career, and changed my personal life, too.

When I was 12 years old, I was just horrible. My parents were ashamed to watch my matches. I would play on a court at the local club and they would watch from the balcony. They would scream, 'Be quiet' to me and I would scream back, 'Go and have a drink. Leave me alone.' Then we would drive home in a very quiet car. No one speaking to each other.
