West Ham United are supporting Sir Bobby Robson National Football Day - with the country coming together in celebration of the nation's favourite game and one of English football's most iconic figures on Saturday 10 August.
In all, 150 community-focused events are taking place across the country with Sir Bobby Robson Day a central part of The FA's 150th anniversary being marked this year - providing a showcase of The FA's work at grassroots level and giving the nation the opportunity to get involved.
Across the country, the day will focus on every aspect of the game including women's football, disability football, refereeing and coaching with other flagship events in London, Manchester, Durham and at St. George's Park in Burton.
Fans are also able to get involved in supporting football with their attendance at matches like Saturday's new season curtain-raiser against FC Pacos de Ferreira.
West Ham manager Sam Allardyce said: "I had the huge honour of both playing against the great Ipswich Town side managed by Sir Bobby and later managing against him during his time in charge at Newcastle United.
"Sir Bobby was not only one of greatest managers that this country has ever produced, but he was also a great man. He was a true gentleman who simply lived for the game and was always on hand to pass on his knowledge when I was manager at Newcastle.
"I am a big supporter of The Sir Bobby Robson Foundation and have taken part in the Celebrity Golf Classic many times. The charity is doing fantastic work on the early detection and treatment of cancer.
"Sir Bobby loved the game at all levels and would have been delighted to have his name associated with National Football Day."
Lady Elsie Robson, Sir Bobby's widow, said: "I'm sure Bob would have been thrilled having a National Football Day named in his honour.
"He was always so incredibly passionate about football. He just loved it, whatever level it was being played at. He was lucky enough to play and manage at the top of the game but he was just as enthusiastic talking to youngsters about their junior club matches."
Sir Trevor Brooking, Hammers legend and The FA's Director Of Football Development, said: "The Sir Bobby Robson National Football Day has been created as part of our 150th anniversary celebrations to showcase the nation's love for the game and the huge number of people who get involved in football every week, whether that's playing, coaching, volunteering or refereeing.
"This day will highlight the sheer breadth of the nation's favourite game and we hope it will encourage more people to get involved. Whether you visit one of the planned 150 events or simply head to your garden or local park with family and friends, there's no better day to get into football."
This October, The FA is once again supporting Sir Bobby's Breakthrough Auction. Organised entirely by volunteers, this online auction will raise funds for the Sir Bobby Robson Foundation, Breakthrough Breast Cancer and cancer services within Suffolk Hospitals.
