Of course it's tough to reach the number one place and also winning grand slams.

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

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

My whole life, I've been working really hard, and I can say I'm a grand slam champion.

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