Preston North End Football Club, an English association football club based in the Deepdale area of Preston, Lancashire, was founded in 1880.
 For their first eight years, there was no league football, so matches were arranged on an occasional basis, supplemented by cup competitions organised at both local and national level.
 In 1888, Preston participated in the inaugural Football League.
 They won the first top-flight league title and of the 22 matches they won 18 and drew the other four, therefore they remained undefeated thus being labelled "The Invincibles".
 They were the only team to be known by this nickname for 115 years until Arsenal completed their 2003–04 season without a defeat.
 Since then the club has remained in the Football League although it has competed in its various divisions.
James Trainer (born 7 January 1863, Wrexham - died 5 August 1915, Paddington, Central London, England) was a Welsh association football player of the Victorian era.

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 The club remained in the Football League until 1992, when its First Division was superseded as English football's top level by the newly formed Premier League, of which they were an inaugural member.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.

 Arsenal participated in the Premier League, FA Cup, League Cup and the UEFA Champions League, after finishing fourth in the previous Premier League season.
 Despite an opening day 1–3 league defeat at home to Aston Villa, which exacerbated underlying anger at the club's inactivity in the transfer market, Arsenal's league campaign got off to a strong start.
 Early pace-setters in the title race, Arsenal led the table for much of the season, spending more time on top of the league than any other side.
 However, a combination of injuries to key players and heavy defeats away from home against other title challengers saw the Gunners' title ambitions evaporate by late March.
 Nonetheless, Arsenal achieved success in the FA Cup with a dramatic 3–2 win over Hull City in the 2014 Final, ending a nine-year trophy drought.
In English football, "The Invincibles" has been used to refer to the Arsenal team of the 2003–04 season managed by Arsène Wenger, and the Preston North End team of the 1880s managed by William Sudell.
 Preston earned the nickname after completing an entire season undefeated in league and cup competition, while Arsenal were undefeated in the league.
