If the day ever comes when I am world No. 1, then great, but for me, the biggest dream was to win a slam, and I did it.

My dream was always to win a grand slam, and my second dream was to be No. 1.

Winning the second grand slam, it was a bit different. I don't have anything to prove anymore. I am at the top: number one.

My grandfather has a big influence on me; without him, I wouldn't be where I am now.

When I was a kid, I was always dreaming to one day be the No. 1 player in the world, to win Grand Slams.

Now I can say I'm a Grand Slam champion, and it sounds really crazy.
