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

One should just be able to play a perfect game.

It's not so simple to just stay in the moment and trust your game and your strength that you can turn it around.

What I think I've been able to do well over the years is play with pain, play with problems, play in all sorts of conditions.

One of my big, big strengths I think early on in my career was that I could learn very quickly. You wouldn't have to tell me the things 10 times or 50 times until I would understand them. You would only have to tell me two or three times.

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.

With all the injury problems we have in men's tennis at the moment, I'm happy to still be standing.
