Sparks are expected to fly from Serena Williams's racket when she finally gets a chance to settle a six-year-old score against Maria Sharapova at tonight.
The last time they met on grass, Williams was a sure bet to complete a hat-trick of Wimbledon crowns as she was facing a virtually unknown 17-year-old in the 2004 women's final.
But somebody obviously forgot to inform the Russian to tell her about her bit part in the final, and instead she memorably tried to calll her mother from Centre Court to tell her "Hi mum, guess what? I just won Wimbledon."
Over the last few months though the three times champion Williams she has taken her grand slam tally to 12 while the 16th \seed Sharapova is still trying to work out how far she can stretch her serving arm after enduring numerous shoulder problems.
