Wimbledon day five: Andy Murray, Serena Williams partnership debuts

Defending champion Novak Djokovic is back in action and Andy Murray will partner Serena Williams in the mixed doubles.

Two former world number ones also face off when Simona Halep takes on Victoria Azarenka.

Here, PA previews the fifth day of action.

Brit watch

With Kyle Edmund and Heather Watson bowing out on Wednesday there are no Brits in singles action. Murray's highly-anticipated partnership with Williams, against Andreas Mies and Alexa Guarachi and hot on the heels of his successful combination with Pierre-Hugues Herbert, tops the doubles bill and will be fourth on either Centre Court or Court One.

Match of the day

Former French Open champion Halep takes on three-time grand slam finalist Azarenka in a tasty third-round tie on Centre Court. Halep is seeded seventh while Azarenka has climbed back up to 40 in the world. Halep won their last meeting, in the last 16 at Wimbledon two years ago, while Azarenka has not beaten the Romanian since 2012.

Potential Upset

Reilly Opelka upset Stan Wawrinka in round two and will fancy his chances of doing the same against 15th seed Milos Raonic out on Court 12. Expect few rallies in a clash of the big servers.
