Against Steve Johnson at the Olympics I was down a couple of times.

I've always been a good returner since my junior days - I don't know why that was.

I've always been lucky enough to just play tennis, so I never actually had a job when I was growing up.

I'm not allowed to make a joke. It is a bit unfair how I'm treated. I thought it was a joke. I got calls and messages. I would rather not to have to worry about things like that. It is disappointing.

I decided at the outset to invest in a fairly broad range of businesses, as I didn't want to get pigeonholed into one sector.

Obviously I would have loved to have won, but I have had a good run every match.

I've realised over the years I play my best when I have time to prepare for each tournament as best as possible.
