Johanna Konta earned an Australian Open showdown with Serena Williams by easing past Russian Ekaterina Makarova to reach the quarter-finals.

Konta, from Eastbourne, needed three sets to overcome Makarova here last year but this was far more straight-forward as the British No.1 sailed through 6-1 6-4 in 69 minutes.

She will now face Williams, the 22-time grand slam champion, for a place in the last four.
