'I think as a guy you need a little bit to be on your own from early on, to start to live your own life, and try to understand what is going on around you, you have to be able to survive...

I'm not fighting with myself. Oh, my God. That's how I am. You know, the story of the hippo? The hippo comes to the monkey and said, listen, I'm not a hippo. So, he paint himself like a zebra. He said but he's still a hippo. He said but look at you, you're painted like a zebra but you are a hippo. So then he goes, you know, like I want be a little parrot. So, he put the colours on him and he comes to the monkey and said but, sorry, you are a hippo. So, in the end, you know, he comes and said I'm happy to be a hippo. This is who I am. So, I have to be who I am and he's happy being a hippo.

It is very hard for me to switch from clay to grass.

There's a lot of things in life that we don't know why they're coming exactly at this moment.

If you get operated, something can go wrong and you can just say bye-bye to tennis. That's what happened to a lot of soccer players in Europe. They get operated, some things, it's not the mistake of the doctor. It's just some surgeries, they just don't go the right way...My injury will never go away. It's already become so chronic there's no chance to fix it so I can play without pain.

Five sets is a kind of lottery. Anything can happen.

That was...that was choking. You're right. But of course when you play against (Roger) Federer, he's No. 1 in the world, he won three grand slams last year, and he's just full of confidence. It's difficult to do anything regular to beat him. You have to do something extra to be able to have the chance to beat him. Set points, I had six of them and I couldn't take one. But I was close.
