Why are English football teams called United?
The above is completely made up. Sheffield United Cricket Club were formed in mid 1850s before any football teams were in existence. This was an umbrella organisation for a number of cricket teams using the Bramall Lane ground. The cricket club formed a football section in 1889 and this team became one of the leading professional football clubs in England in the late 19th century. Any other club such as Newton Heath in Manchester simply copied the name United from Sheffield United when they decided to rename their clubs because they liked the name United more than Rovers or Wanderers or County etc (and definitely liked it more than Wednesday).
