I fear no one, but respect everyone.

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

I don't need to come back to Wimbledon every year because I can't live without it. I'd be totally cool without tennis.

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.

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.

I've always been aware that the image you patiently construct for an entire career can be ruined in a minute. It scares you a bit, but that's the way things are.

Tennis can be a very frustrating sport. There is no way around the hard work. Embrace it. You have to put in the hours because there is always something you can improve. [Y]ou have to put in a lot of sacrifice and effort for sometimes little reward but you have to know that, if you put in the right effort, the reward will come.
