Australian Open 2017 Day 4

Denis Istomin

"It is unreal. To beat Novak in five sets, it's a great win, you know. I'm still feel tired little bit. I didn't expect what I'm doing now and what I did on the court. I like the way I am playing. I mean, I feel just tired. I don't think about that I win against No. 2 in the world."

Ekaterina Makarova

Grigor Dimitrov

Caroline Wozniacki

Johanna Konta

"I think in turn, a lot of it is time. And then a lot of it is also, I don't know what it is about fate or being in the right place at the right time. I think some things need to come together, and, yeah, I love what I do, so hopefully I'll be around for many more years with my body staying healthy."

Dominika Cibulkova

Milos Raonic

Rafael Nadal

"I know I have been working great. I know I have been working a lot and very well. I have been practicing at high level. So every time that I have the chance to go on court, I am able to have more confidence on what I'm doing. I have now a chance after tomorrow. That's an important thing for me. I'm very happy for that."

"I'm happy with the way I'm playing right now. Nothing much to improve. Just a few tactical things against players that I'm playing. I've been playing some big hitters the whole Aussie summer, to be honest. I'm just hustling."

Dominic Thiem

Serena Williams

"Honestly, it's not ideal. But at the end of the day, when I play players like Bencic and Safarova, they force me to play better. It forces my game from the very first day to be at a high level. So I think it's actually good. You know, I needed something to start really fast. I'm not going to complain about it."
