Andy Murray will feel fortunate to have avoided a quarter-final date with Tomas Berdych, however his conqueror, Stanislas Wawrinka, will pose a serious threat to the defending Champion.
Sky Sports commentator Nick Lester looks at the men's quarter-final matches, two women's quarter-final matches and the semi-final between Serena Williams and Na Li on this edition of the podcast.
