Radwanska headlines Sydney draw
Poland's Agnieszka Radwanska will lead a field featuring seven of the top 10 women players for next month's Sydney International, organisers said on Thursday.
World No 4 Radwanska is the likely top seed but will face a fierce challenge from three Grand Slam champions, China's Li Na, the Czech Republic's Petra Kvitova and Australia's Samantha Stosur.
Angelique Kerber, French Open finalist Sara Errani and former world No 1 Caroline Wozniacki are the other top 10 players in the draw.
The men's line-up features the French pair of Jo-Wilfried Tsonga and Richard Gasquet.
The Sydney International takes place from January 6 to 12.
