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.
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.
For me, by far, the Olympics is the biggest sporting event in the world.
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.
Tennis is an individual sport, and I am quite a self-conscious person.
