Clare Balding tells the story of how football went from an amateur pastime to big business and it all started in the Lancashire mill town of Preston. In the season of 1888-89 The Invincibles, as the Preston team were known, were unbeaten in the League and the FA cup, becoming football's first double winners. As Professor Matthew Taylor of De Montfort University explains, their success was down to the vision of one man, their manager, William Suddell, a local mill manager. Clare visits Deepdale, Preston's ground to find out how Suddell became the 'father' of professional football.
