Clijsters returns to New York keen to see off challenge of Wozniacki

Twelve months ago Clijsters completed a remarkable return to the sport after previously retiring in 2007, beating Denmark's Caroline Wozniacki in the final in only her 14th match and third tournament of what she likes to call her "second career".

Her 18-month-old daughter Jada was in the stadium to see Clijsters become the first mother to win a Grand Slam since Evonne Goolagong Cawley beat Chris Evert to win Wimbledon in 1980.

A year on, Wozniacki is the top seed in New York in the absence of injured world No 1 Serena Williams, but Clijsters's greater experience makes her the favourite to win a third US Open title. "My attitude is not any different compared to last year," Clijsters said.

"Obviously last year had a few more unanswered questions but I think this year I know what I have to do if I want to try to do as well as I did last year.

"I don't feel any more pressure... pressure is a good thing. Pressure is a sign they're putting you in the spot of maybe being one of the favourites. So I'm excited to be back to defend my title.

"The little details you kind of forget about but once you come back it's the little details that freshen everything up a little."

"She (Wozniacki) is a great player, you don't get there by luck or by a wild card or anything," added Clijsters, who was actually a wild card herself when winning here last year, joining former Wimbledon champion Goran Ivanisevic as the only wild cards to win a Grand Slam.
