Former world number one Caroline Wozniacki says she believes she can get back to being world number one after a difficult 2012.
The Dane swept past Urszula Radwanska 6-1 6-2 in the first round of the Sydney International ahead of the Australian Open in Melbourne.
Wozniacki, who is yet to win a major, slipped from number one to a world ranking of 10 in 2012 but her win over Radwanska showed she is set for a big year.
“Within myself, I believe I can get back there, but it’s a lot of hard work and there are a lot of great players so you never know what’s going to happen,” Wozniacki said.
“The most important thing is that you’re healthy and I’m going to play as best I can and win as many tournaments as I can and the ranking will come if you play well, but the most important thing is the health.”
