When you are young, you are a little naive.

That's why we have journalists, for stats.

I don't worry about what my opponent is doing.

People always ask about young people like me being forced into things. I play tennis because I love it. I think Russians might be tougher than other people. When I arrived in America I was young, but I already knew what I wanted. I think that when you start from nothing, when you come from nothing, it makes you hungry. I am proud of where I came from and I know what I want. I want to win.

After being on the court for six hours, being on TV is very glamorous and fun for me. But tennis is always going to be my priority. It's not going to be this thing when all of a sudden TV will get in the way of that.

I love getting consumer reports. I think it's one of my favourite things, studying what people have to say about the product and then trying to make it better.

I never really had an idol.
