Uniquely, in 2008 three of the four semi-finalists (Barnsley, Cardiff City and West Bromwich) were from outside the top division, although the eventual winner was the last remaining top-flight team, Portsmouth. West Bromwich (1931) are the only team to have won the FA Cup and earned promotion to the top flight in the same season; whereas Wigan Athletic (2013) are the only team to have won the Cup and been relegated from the top flight in the same season.

The feat was repeated twice over the next seven seasons (by Southampton in 1976 and West Ham United in 1980) but has not been accomplished since. In 1980, West Ham United became the last side to date to win the competition from outside the top division in football. They were a Second Division outfit when they beat holders Arsenal 1–0 thanks to a goal by Trevor Brooking. Four second-level clubs – Queens Park Rangers in 1982, Sunderland in 1992, Millwall in 2004 and Cardiff City in 2008 – have since reached the final, though all 
Title: FA Cup
Content:  The FA Cup has only been won by a non-English team once. Cardiff City achieved this in 1927 when they beat Arsenal in the final at Wembley. They had previously made it to the final only to lose to Sheffield United in 1925 and lost another final to Portsmouth in 2008. Cardiff City is also the only team to win the national cups of two different countries in the same season, having also won the Welsh Cup in 1927. The Scottish team Queen's Park reached and lost the final in both 1884 and 1885.

As of 2021, the record for the most wins is held by Arsenal with 14 victories. The cup has been won by the same team in two or more consecutive years on ten occasions, and four teams have won consecutive finals more than once: Wanderers, Blackburn Rovers, Tottenham Hotspur and Arsenal. The cup has been won by a non-English team once: Cardiff City in 1927. The cup is currently held by Leicester City, who defeated Chelsea in the 2021 final.
Title: 2008 FA Cup Final
Content:  The 2008 final was the first time since 1995 that the competition would be won by a team other than the "big four" of English football, Manchester United, Arsenal, Liverpool and Chelsea. It was also the first final not to feature one of the four sides since 1991. Cardiff were appearing in their third FA Cup final, having lost to Sheffield United in the 1925 final before becoming the only team from outside England to win the competition in 1927 by defeating Arsenal. Portsmouth were appearing in their fourth final; they had suffered defeat in both the 1929 and 1934 finals before becoming the last team to win the competition before World War II in 1939. This was the first

The 2016–17 FA Cup had two non-League teams reaching the fifth round; Lincoln City and Sutton United, both of the National League. Sutton United's run included a 3–1 win away to League One side AFC Wimbledon in a third round replay and a 1–0 win at home to Leeds United of the Championship in the fourth round, before succumbing 2–0 to eventual winners Arsenal in the fifth round. Lincoln City became the first non-League side in 103 years to reach the

Sunderland won the cup in 1973, Southampton repeated the feat in 1976, and West Ham United won in 1980, the most recent victory by a team from outside the top division. Until 1999, a draw in the final would result in the match being replayed at a later date; since then the final has always been decided on the day, with a penalty shoot-out as required. As of 2020 a penalty shoot-out has been required on only two occasions, in the 2005 and 2006 finals. Arsenal hold the record for the highest number of FA Cup wins, having claimed the trophy 14 times, most recently in 2020.
Title: List of non-League clubs in the Fifth Round of the FA Cup since 1945
Content:  The most recent example of a non-League team beating top-flight opposition in the FA Cup was Lincoln City's Fifth Round victory away at Burnley in 2017. The last time a non-league side beat top-flight opposition at home in the FA Cup was Sutton United's Third Round victory over Coventry City in 1989. In 2017, two non-League teams made it to the Fifth Round of the competition, Lincoln City and Sutton United. This was the first time two non-League teams had made it this far in the same season since the establishment of the Football League in 1888. Lincoln City subsequently became the first non-League team in 103 years and the first since World War I to make the quarter finals, but lost 5–0 to Arsenal.
Title: FA Cup
Content:  Since the creation of the Football League in 1888, the final has never been contested by two teams from outside the top division, and there have only been eight winners who were not in the top flight: Notts County (1894); Tottenham Hotspur (1901); Wolverhampton Wanderers (1908); Barnsley (1912); West Bromwich Albion (1931); Sunderland (1973), Southampton (1976) and West Ham United (1980). With the exception of Tottenham, these clubs were all playing in the second tier (the old Second Division) – Tottenham were playing in the Southern League and were only elected to the Football League in 1908, meaning they are the only non-League winners of the FA Cup since the League's creation.

Tottenham Hotspur, then of the Southern League, defeated Sheffield United of The Football League to win the 1901 final. A year later Sheffield United returned to the final and won the cup, which then remained in the hands of Northern and Midland clubs until Tottenham won it again in 1921. In 1927, Cardiff City, a team which plays in the English football league system despite being based in Wales, won the cup, the only non-English club to do so. Scottish club Queens Park reached the final twice in the early
