Williams knocks champion out of Wimbledon

Serena Williams was at her brilliant and brutal best on Wimbledon’s Centre Court today as she sent defending champion Petra Kvitova home at the quarter-final stage.

Without a grand slam title since her fourth Wimbledon two years ago – her 13th in total – she is in London with a point to prove and sent out a clear warning sign of her intentions with a 6-3 7-5 win.
