Serena Williams

The fifth woman in history to hold all Grand Slam titles at the same time with her victory in the 2003 Australian Open, but uncertainty still surrounds the fitness of the former world number one.

Age: 22

Lives: Palm Beach Gardens, Florida

Plays: Right-handed, double-handed backhand

Grand slam titles: Six (US Open 1999, 2002; Wimbledon 2002, 2003; French Open 2002; Australian Open 2003)

Record at Wimbledon: 2003-winner, 2002-winner, 2001-quarter-final, 2000-semi-final, 1998-third round.

The absence of Belgian duo Justine Henin-Hardenne and Kim Clijsters has left the way clear for the American to complete her recovery following knee surgery last year by clinching a third consecutive All-England Club crown.

The younger Williams sister has shown patchy form this year but her power-based game is well suited to the slick London grass.

Serena will also doubtless reveal her latest line of tennis dress designs. The conservative All England Club will expect a more tasteful take on the dubious pink outfits she wore at the French Open.
