Arsenal F.C. league record by opponent: Arsenal Football Club is an English professional association football club based in Holloway, London.  The club was formed in Woolwich in 1886 as Royal Arsenal before it was renamed Woolwich Arsenal in 1893.  They became the first southern member admitted into the Football League in 1893, having spent their first four seasons solely participating in cup tournaments and friendlies.  The club's name was shortened to Arsenal in 1914, a year after moving to Highbury.  In spite of finishing fifth in the Second Division in 1915, Arsenal rejoined the First Division at the expense of local rivals Tottenham Hotspur when football resumed after the First World War.  Since that time, they have not fallen below the first tier of the English football league system and hold the record for the longest uninterrupted period in the top flight.  The club remained in the Football League until 1992, when its First Division was superseded as English football's top level by the newly formed Premier League, of which they were an inaugural member.  In 2003–04, Arsenal completed a league season without a single defeat, something achieved only once before in English football, by Preston North End in 1888–89.

List of Bristol Rovers F.C. players: 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.
