If you want a player to serve and volley more, you need to teach them to do that more, how to move at the net.

Staying more controlled mentally stemmed from taking my fitness more seriously. When you're doing track work, sprints and so on, it's pretty painful, but that does make you feel better prepared and therefore mentally stronger when you're going into a match. You know, without a doubt, that you are strong enough to last.

I had great success with Ivan Lendl. Was he a perfect coach? No. Was he a very good coach? Yeah. He had some very strong qualities and some things that weren't so good.

Everyone has to try to give back as much as possible because I think in all sports it helps kids to have role models or people to look up to. Someone like Jess Ennis, I know a lot of young girls have started to get into athletics stuff because of her, because of her success.

Everybody always talks about the pressure of playing at Wimbledon, how tough it is, but the people watching make it so much easier to play.

Earlier in my career, I used to spend a lot of time practising my tennis on court. Now I've learned that it's better to do just a couple of hours on court and two gym sessions a day. That's what's made me fitter and stronger.

You have to go into each match believing you can beat all of the players.

I do some 400 m. repetition running for endurance on the court. I'll be in the gym lifting weights, or I'll be putting in a lot of core stability to work to improve my balance.

It's easy to start over-thinking things and over-analysing things.

I do think your personal life has an impact on your tennis. If your private life is up and down, and you're thinking about what is going on back home, then you aren't solely focused on your job, but when things are good back home, it's so much easier when you're on court. It's not necessarily marriage; it's more having a stable relationship.

There's two people I would say to try to go and watch who are probably the future of tennis. One girl called Taylor Townsend, she got a wildcard from the event into Wimbledon; she's an American girl. On the men's side, there's an Australian guy called Nick Kyrgios; he's 19, and he was the number one junior in the world.

You are always talking about yourself and tennis and how you are feeling. I try to avoid it when I don't have to.

People say to me, 'You don't seem that interested in interviews.' Well, you know, I'm not, often. I'm not going to talk tactics with the press, so you are left with talking about how you are feeling; for me, it is not the most interesting thing to be doing.

For me, by far, the Olympics is the biggest sporting event in the world.

One of the things I would have loved to have had was a family that worked better together, although I love my mother and father to bits.

You can't focus on other people's careers. Everybody is different.

A lot of times, the press guys ask why I take an hour and a half to come to the interview room, but if you don't do the massage and the ice baths and the stretching and the cooling down and the eating, and your opponent is doing that stuff, they already have an advantage.

I feel like I'm more a fan of tennis rather than it being men's or women's. I enjoy watching doubles as well when it's on. I think that there are certain players that I enjoy watching on the men's and women's side. There's some players that I don't enjoy watching on both sides.

I often find that pundits are quite negative... not just in tennis, but in sport in general. I just don't like that. Obviously, the job of a pundit is to create interest and a bit of controversy. I get that. Listeners like that. But I do think there's a duty there to promote the sport and talk about how good these people are at what they do.

A lot of the players are very complimentary about each other; they embrace at the end of matches because the level of the tennis has been so good. I think that's something that tennis has got to be proud of.

Obviously you try to keep as much of your private life as private as you can.

I don't play any tournaments to come second best.

When I'm at home, I enjoy going go-karting.

Boxers risk a lot in the ring. That's one of the things that attracts me to it. You want to see a knockout but I also really don't want to see people get hurt. It's this constant dilemma when I'm watching boxing. The only times I get nervous is watching a really big fight or when my brother is playing. I get to the stage where I'm actually shaking.

Getting married is great, and I feel really good away from the court, and my private life and stuff is good. But you still need to train and work hard. Like, I didn't go on a honeymoon after we got married; I went to Barcelona and trained for 10 days to get ready for the clay-court season. It's been good, but you still have to put the work in.

A lot of athletes use sports psychologists.

My fitness trainer's English, my physio's English, some of my friends are English. I don't have a problem with English people at all.

To be honest, I think bananas are a pathetic fruit.

I just enjoy watching tennis. And there's things that you can learn from the men's and the women's game.

When a lot of things are going the wrong way for a country, for a people, when you can't really think of anything worse than a war, you always try to take life on the brighter side and that's how I grew up with my parents.

When I'm in Miami I like to go and watch basketball, the Miami Heat.
