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 don't think I'm easy, but I think I'm quite a good worker.

For me, tennis is a sport. It's not a job, it's a sport.

I won't lie to you. It's better to have someone to help you. I need it...

I care about the match. I don't care about, you know, other things. It's like if I'm not happy, it's okay. I want just to be happy, you know. If I'm not happy, fine. Have it, you know.

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

When I feel good, the crowd is behind me, have a great spirit, I think I can be very tough to beat.
