She is the oldest world No 1 in the history of women's tennis and many believe she is the greatest player ever to have picked up a racket,asics gel nimbus 14 mens but Serena Williams' hunger remains undiminished. The 31-year-old American's domination has probably never been greater as she faces Victoria Azarenka in the final of the US Open here today.
There have been blips along the way – most notably defeats by Sloane Stephens in the quarter- finals of this year's Australian Open and to Sabine Lisicki in the fourth round at Wimbledon - but the evidence of the last 15 months suggests that Williams is a better player than ever. She has won 13 of the last 18 tournaments she has played, including Wimbledon and the US Open in 2012, the Olympics, the WTA Championships and the French Open.
With 16 Grand Slam singles titles to her name, the question now is whether Williams can become the most successful female player of the Open era.
The record for Grand Slam singles titles is held by Steffi Graf, who won 22. Chris Evert, who is tied in second place alongside Martina Navratilova with 18, believes that Williams has time on her side,asics onitsuka tiger uk given that she has always played fewer tournaments than most and has had periods away from the game through injury.
