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.

I’d much rather win in three or four sets than go the distance all the time; I seem to put everyone through the wringer quite a bit.

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

I don’t know. Haven’t I always been mature?

He’ll go down as one of the guys who changed our sport in a lot of ways, not only the way he played the game, but also the way that he conducted himself on and off the court.

I’m fortunate: I can play as long as I want to play. There’s no coach or trainer who is going to say to me that I’m dropped or sacked, it’s time to move on. I can play as long as I want to play.

I’m one injury away from hanging up the racket at any time.

My video game character is a bit better looking than me, actually. I don’t think he has to worry about his hair getting messed up.

Everyone has to call ‘time’ at some stage.

I feel like when I’m match tough and match hard and played a lot of matches I got that competitive winning spirit going and I can get on some rolls like I did last year. I won San Jose, Indian Wells and made the semifinals in Miami so it can happen for me.
