I'm a very good sleeper, especially during a tournament; I usually get eight hours a night, even before a big match.

When you step out on the grounds of Wimbledon, you feel that respect, you feel that heritage, feel the history.

I know what I have to do in order to do good.

Who wouldn't want to practice with the No. 1 player in the world?

The first time I heard 'Baby Federer,' I was maybe 16. After that, it sort of took off.

At some point in your life, you need to sit down and say, 'What do I want to do? How do I want to be remembered? What's my legacy? And what's important to me?'

It's very hard to look at the man in the mirror. Because you can't hide anything.

I can take five showers in one day.

I don't like taking showers in the locker room after a match.

I get manicures and pedicures because I don't want to be one of those guys with messed-up hands and feet.

I think when I was younger, I was struggling to kind of differentiating love from a personal love or a tennis love or whatever else. There was time that I wasn't sure how to deal with both things in the same time. But you learn. I guess we grow. I mean, I don't want to say I've learned from my mistakes, but I've learned myself a little bit better.

All I'm focused on is playing my game. Everything else will take care of itself.

I've always been a very easy-going person.

I even remember the first contract I ever signed. I was 13 or 14... my dad said, 'It's your choice. It's your life.'

It would be difficult to pick out one shot as my main strength, as I like all my shots, and I can do anything on any surface.

I believe in my abilities, as when I get things right, things happen for me.

Let's forget the cliche on girlfriends, from Serena to Sharapova. I say it's easy to get lost in beauty, but is it a mistake then?

The negative talk, everything that has been coming my way, I don't care about it.

Obviously, it's tough when you lose a match, but that's how it goes.

Tennis is a great platform for me to do well, and for sure, I want to be No 1, to win Slams, but there are more things that I want to do.

We all know how to play tennis. We all know how to hit the ball. It's more just about those details - managing all those early rounds and just managing yourself to make sure you're ready for whatever is coming up next.

I know tennis is just a game, but it's something that it can actually unite us even more.

I believe that if you feel good and if you look good when you're playing, it can give you the extra edge that you might need.

If you look good, it brings confidence.

For me, I like that, how do you say, bohemian sort of look. Baggy sweaters to really fitted pants - I love Rick Owens's stuff, for example. I am really into that kind of grungy style.

I think tennis was just in my genes.

My father loved the single-handed backhand, so to him, that was the main goal; we were always fascinated by that shot. He taught me all the technique and how to structure my game. I was really privileged to have a father like that.

In the beginning, I thought the Federer comparisons were cool, but after a while, I wasn't happy with it. It's not the best thing you can hear as you're trying to develop, as it puts extra pressure on a young kid.

Trust me: it's no fun where we're on the fourth set, or you've got to serve second serve on a break point down.

I get that I can come across as a show-off, but that is part of who I am.

Everything is customised, from my watches to my phone. I like my things to be different.

I have always been the kind of guy to adjust to anything. I never cared where I was going to sleep or what court I was going to practise on.

I'd love to have a line of tennis clothes, something unique and different.

I especially like Lanvin.

The biggest pressure is what I put on myself.

I'm bad at going on vacation.

I appreciate where I come from. I never forget.

I've always felt that's something I'm capable of doing - setting up a trend.

I think mental preparation is really important. Every day, you've got to imagine your goal.

To be able to represent Nike as a brand is one thing, but to also represent the great players that came before me means a lot.

You may not be playing your best tennis or having your best match; sometimes it's just not your day. The important thing is to believe in yourself, which starts with being confident in your abilities.

Sometimes confidence is everything.

I come from a very sporty family.

My mom is a former volleyball player.

Tennis is such a fun game. One of the things that I really like is that everything depends on you. Before certain matches, you might have those butterflies, but that's the excitement. There's a ton of emotion that you're going through.

I never thought I was going to make a career out of tennis, to be honest, until I was 10 or 11 years old. One of my earliest memories is when I was seven, and I was competing against players that were three, four years older than me. I didn't take it too seriously at the time. I was having a lot of fun.

Tennis is very tough.

I like clothes a lot.

I want to create my own legend, my own trademarks.

I've always been a fighter. I can get pretty feisty sometimes.
