For sure it's better to have a coach. I won't lie to you. It's better to have someone to help you. I need it, you know. But as I say all the time, it's not easy to feel someone. That person has to be - has to be, for me, like good, first of all, but has to be hard and also understand my personality.

I think I play tennis for, to against a big legend, big court, short time. That's what I train for. That's why every day I wake up and I wish I could play those matches, you know. It's like, for me it's the best thing can happen is to play against that guy on that stage, you know.

When you've played a long rally and you lost it, it does hurt.

I think I always play good, always played solid.

Sometimes, you know, I just feel like I want a Coke, and I drink a Coke.

If you want to talk, it's okay with me. I sit and relax.

My first objective is to win against No. 1 in the world.
