Keys: "It's hard to live in hotels".

Madison Keys has qualified for the quarter-finals of the Australian Open, beating Elena Rybakina.

The American is used to playing important matches, having already contested a Grand Slam final, at the US Open in 2017.

In a press conference, she spoke about her experiences in professional tennis: "I've had some great years, but also some tough seasons.

Overall, I think I've been consistent. I think part of that is going out to enjoy and surrounding myself with good people along the way.

It's very difficult to practically live in hotels. That's the most complicated part of this sport, on top of having to compete every day."

She will face Elina Svitolina for a place in the semi-finals in Melbourne.
