Navratilova takes aim at Wozniacki

TENNIS legend Martina Navratilova has declared current world number Caroline Wozniacki unworthy of the top ranking and has condemned the system that put her there.

The winner of 18 grand slam singles titles believes Serena Williams is the best player in the world, but in her absence as a "full-time'' player, fellow Czech Petra Kvitova is the rightful women's number one.

Navratilova says six years ago when they were giving bonus points for beating players, Kvitova would have ended up number one.

The comments may well fire up Wozniacki this afternoon in her quarterfinal clash with defending champ Kim Clijsters at the Australian Open.
