Agnieszka Radwanska is looking to maintain her perfect start to 2013 when she meets Li Na in the Australian Tennis Open quarterfinals today.
The ASB Classic champ is yet to drop a set in her 13 wins this month, including a victory over Li in Sydney.
The fourth seed just wants to keep her form going having not dropped a set this year.
The last time Li reached the quarterfinals of a major, she won the French Open in 2011.
The other women's quarter final today sees Ekatarina Makarova against Maria Sharapova.
David Ferrer battles Nicolas Almagro and Novak Djokovic plays Tomas Berdych in the men's quarters.
