Passage: Sheffield has a long sporting heritage. In 1857 a collective of cricketers formed the world's first-ever official football club, Sheffield FC, and the world's second-ever, Hallam FC, who also play at the world's oldest football ground in the suburb of Crosspool. Sheffield and Hallam are today Sheffield's two major non-league sides, although Sheffield now play just outside the city in nearby Dronfield, Derbyshire. Sheffield and Hallam contest what has become known as the Sheffield derby. By 1860 there were 15 football clubs in Sheffield, with the first ever amateur league and cup competitions taking place in the city.
