Video: Prince William warns Buckingham Palace football match players not to break a window Prince William, president of the Football Association, presented the hardworking helpers with medals recognising their efforts during a palace reception, part of the FA's 150th anniversary celebrations. Later this afternoon Civil Service FC and Polytechnic FC, both based in Chiswick, west London, will play a Southern Amateur League fixture in the gardens of the famous landmark - the first time a competitive match has been held at the Palace. The Duke told the guests who included former England striker Michael Owen and FA chairman Greg Dyke: "At its best, football is a powerful force for good in society. I believe over its 150 years, football has remained a wonderful example of the power of community and of our ability to come together to organise and to enjoy a simple pastime. The Duke has helped organise the match and the Queen gave her permission for it to be staged at her official London home. Wembley groundsman Tony Stones and his team worked with the royal household gardeners to create the pitch in the 39-acre garden. Prince William joked that if a window was smashed the footballer would have to face his grandmother. He said: "This magnificent home, Buckingham Palace, is at the heart of the nation, and so there cannot be a more fitting setting to celebrate our national game, and to celebrate all of you. I cannot tell you how excited I am that later today we will be playing football on my grandmother's lawn.
