Melbourne, Jan 24 (IANS) Caroline Wozniacki will lose her World No.1 ranking after her quarter-final defeat by defending champion Kim Clijsters at the Australian Open here Tuesday.

The 21-year-old Dane first became No.1 in October 2010 at the China Open in Beijing and she has occupied the top spot all through, except for one week last February when Clijsters briefly took over.

But her 3-6, 6-7 (4-7) loss Tuesday ensured her reign will end when the new ranking list is released next Monday.

According to the WTA website, Petra Kvitova and Victoria Azarenka will be ranked ahead of Wozniacki in the latest rankings. And so will be Maria Sharapova if she advances into the semifinals of the Australian Open.

“To be honest, I don’t really think about it. I have been there for a long time already,” Wozniacki said.

“I finished number one two years in a row. We are just in January. In the end of the year you see who has played the best, most consistently all year round. I will get it back eventually, so I am not worried.”

Wozniacki, who has long been questioned because she has never won a Grand Slam, said that she has plenty of time to win.

“I start laughing every time the media talks to me like I am finishing my career and I only have one year left and time is running out,” she said.

“The fact is I still have quite a few good years in front of me. I will still improve. I still have a number of Australians and a number of US Opens and Wimbledons and French Opens left.”

“I will definitely do my best and try to win one or even more. In the end, you can just do your best. You can’t do anything more than that,” she added.
