The Independent will be showing highlights from selected Australian Open matches between January 19 and February 1.
Serena Williams will meet Dominika Cibulkova in this year's Australian Open quarter-final after the latter beat two-time champion Victoria Azarenka in the fourth round.
Cibulkova lost last year's final to China's Li Na and had to face a strong showing from the Belarusian in a match that ended 6-2, 3-6, 6-3 after over two hours of play.
The 25-year-old from Slovakia hit 44 winners and broke Azarenka twice in a thrilling game.

Elsewhere, Serena Williams beat Spaniard Garbine Muguruza after going a set down. The victory was a sweet one for Williams having lost to Muguruza in the French Open last year in one of the competition's shock results. Top seed Williams avoided an early scare to beat the 21-year-old in three sets and she will now face Cibulkova in the quarter-final.
Williams has won the Australian Open five times but has not held the title since 2010 when she defeated Justine Henin.
