"We will miss Kim"

"We will miss Kim"

Ana has paid tribute to her friend Kim Clijsters, the four-time Grand Slam champion and former world No.1 who retired last week.

"Kim was one of the most popular players in tennis, not just for her generation but for a long time," said Ana. "It's hard to think of someone who was so well-liked among the players, fan and officials in tennis.

"I was fortunate to become friends with her early during my career and it was always fun to catch up with her in the locker room.

"She is a very friendly, humble girl and was always interested in how my career was going. We're definitely going to miss having her on the Tour, but I am sure we will see her from time to time when she visits tournaments."

Belgian Clijsters made her WTA Tour debut in 1997. She amassed 41 singles titles and, after losing in the final of four previous Grand Slams, won the 2005, 2009 and 2010 US Opens, followed by the 2011 Australian Open.

She spent a total of 10 weeks as the world No.1 in singles, and is one of only six women in the history of women's tennis to have held the No.1 ranking in singles and doubles simultaneously.
