It's very expensive to be a professional tennis player with all the travel and the flights and the hotels and everything.

I think I'm a really tough player.

I actually had a small kangaroo - and I'm not kidding this time. I was holding a small kangaroo, baby kangaroo ... it was very nice to me this time. Do you know what it did afterward? I gave it some milk, and it just spit it all over me. I was like, Is this a thank-you for just being nice and petting the kangaroo? I got milk all over myself. I guess I deserved that from the story last year.

Young players are starting to come up as well and they will see me as one of the older, experienced ones.

On grass, it can be the small things that decide a match.

I start laughing every time because the media talks to me like I'm finishing my career and I only have one year left and time is running out.

I try to be myself and, of course, be a good role model. I don't really find it hard, but you think about what you do and that other people look up to you.
