My game is a lot about footwork. If I move well, I play well.

Mentally, I'm not ever going to go away.

I did all the right things in so many tournaments. But like I said, sometimes in sports it just goes the other way. Maybe you've already won so much that it evens it out a bit sometimes. I don't know.

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.

Once you find that peace, that place of peace and quiet, harmony and confidence, that's when you start playing your best.

My heart is in South Africa, through my mum. My mum being from here, me spending a lot of time here as well, I feel most connected to this part of the world.

I am a very positive thinker, and I think that is what helps me the most in difficult moments.
