BBC2, 9pm Engineering Archie - Archie Leitch, Football Ground Designer The second in a series of English Heritage titles to celebrate the nation's sporting history comes from the pen of Simon Inglis, author of Football Grounds Of Britain. This particular tome covers the work of consulting engineer and architect Archibald Leitch, who started designing stadiums in 1899 for the likes of Arsenal, Liverpool, Manchester United and Glasgow Rangers.
Alas, for the Leitch legacy, stadium requirements post Hillsborough mean only 12 of his creations still exist. Copiously illustrated throughout, the book is an absorbing account of his achievements. Another famous Archibald Leatch changed his name to Cary Grant and went on to star in films by Alfred Hitchcock. Hitchcock directed Psycho, which happened to be the nickname of footballer Stuart Pearce who played at most of the grounds mentioned in the book. Now, isn't that interesting?
