Serbia's Novak Djokovic celebrates winning the first round match at the Wimbledon Tennis Championships in London

Wimbledon is now in full flow: day four saw showboating, trickery and a shock exit in Rafael Nadal. And the schedule for day five seems like it will be equally entertaining.

Heather Watson, the British No 1, is in action against the 20 grand slam winner and World No 1, Serena Williams. Watson will have her work cut out but she will go into the game knowing all the pressure will be on Williams to add to her outstanding trophy haul.
