I never expected i, in the first place, when I started playing tennis, that I would ever carry the flag into the Olympic Stadium for an Olympic Games... So for me that was a surprise and a huge honor in my life to be able to represent Switzerland.

I'm as patient a father as I am on the tennis court. It takes a lot for me to get really upset, but sometimes kids can get you really cross if they really keep bugging you.

I always believe if you're stuck in a hole and maybe things aren't going well you will come out stronger. Everything in life is this way.

For me, it's important that a fan can buy something that is related to me. Like in soccer, you buy a shirt and it's got somebody's name on the back. That's kind of a cool thing.

It is always in my mind still that I can crush anybody. That's not an issue. But I think that is the same for most athletes. If you don't believe you can win tournaments anymore, then you can't do it.

What I think I've been able to do well over the years is play with pain, play with problems, play in all sorts of conditions.

Confidence? Are you kidding me? I mean, please. Look, some players grow up and play like that. I remember losing junior matches. Just being down 5-2 in the third, and they all just start slapping shots.
