 It is Plymouth's only professional football team, however the city used to have another team called Plymouth United F.C. dating back to 1886.
 The club takes its nickname from the group of English non-conformists that left Plymouth for the New World in 1620: the club crest features the Mayflower, which carried the Pilgrims to Massachusetts and the club's mascot is named Pilgrim Pete.

Colchester United Football Club is an English professional football club based in Colchester, Essex, that was founded in 1937.
 From the 1937–38 season, the club played in the Southern Football League until 1950, when they were elected to the Football League.
 After playing in the Third Division South for eight seasons, Colchester remained in the Third Division when the league was re-organised by finishing 12th in 1958.
 The club were relegated to the Fourth Division in 1961, but made an immediate return to the Third Division after finishing the 1961–62 season in second position, one point behind Millwall.
 They bounced between the Third and Fourth divisions until 1990, when the club were relegated from the Football League for the first time in 40 years.
 After two seasons in the Football Conference, the U's were promoted back to the Football League after winning the Conference title on goal difference over Wycombe Wanderers in 1992.

Bristol Rovers Football Club is an English professional association football club based in Bristol, who play in Football League One, the Third tier of the English football league system, as of the 2016–17 season.
 The club was formed in 1883 under the name Black Arabs F.C. playing their home games at Purdown in Bristol, but they used the name for only a single season, becoming Eastville Rovers and moving to a site known as Three Acres in 1884.
 Eastville Rovers were somewhat nomadic, moving home in 1891 to the Schoolmaster's Cricket Ground, in 1892 to Durdham Down, and in 1894 to Ridgeway, before finally settling at Eastville Stadium and changing their name to Bristol Eastville Rovers in 1897.
 Two years later they adopted their current name of Bristol Rovers when they became founder members of the Southern League.
 They remained at Eastville Stadium for 99 years, before leaving in 1986 when financial pressures meant that they could no longer afford to pay the rent, whereupon they moved to Bath City's Twerton Park, a move that saved the club £30,000 a year.
 After playing for ten years in Bath, the club returned to Bristol in 1997 when they agreed to share Bristol Rugby's Memorial Stadium.
 Since joining The Football League in 1920, when the top division of the Southern League effectively became the Football League Third Division, Rovers have spent most of their time in the second and third tiers of the English football league system; the team has never played in the top flight and spent six years, 2001 to 2007, in the fourth tier.
