I am two different people. What you see on the court is just natural for me. I wear my heart on my sleeve. I have always said 'C'mon' purely to fire myself up. Off the court, I am a lot shyer. I stick to my team and my family and people I trust.

When I go out to play, I still believe I'm as good as anyone out there. I don't have to prove anyone wrong. I know what I've done and how well I can play.

I'm an outside chance at Roland Garros but my focus is really on Wimbledon where it is realistically between me and Roger Federer to win.

I was actually really happy with where my game was at. That's probably the most disappointing aspect.

Why'd you leave the match, huh?

Maybe if you're playing in London or America, you don't feel that pressure quite as much.

Everyone has to call 'time' at some stage.
