 The match was contested by Arsenal and Aston Villa at Wembley Stadium in London.
 The match was played on 30 May 2015 and was the final match of the competition.
 Arsenal won the match 4–0 with goals from Theo Walcott, Alexis Sánchez, Per Mertesacker and Olivier Giroud, for a record 12th title.
 This was the sixth FA Cup win for manager Arsène Wenger, putting him in joint-first place for wins with George Ramsay.
Theo Walcott
Theo James Walcott (born 16 March 1989) is an English professional footballer who plays as a forward for Premier League club Arsenal and the England national team.
1979 FA Cup Final
The 1979 FA Cup Final was a football match played on 12 May 1979 at Wembley Stadium.
 The match was contested by Arsenal and Manchester United.
 It is widely regarded as one of the greatest-ever finishes in an FA Cup final.
 For over 85 minutes the game had been unremarkable, with Arsenal taking a 2–0 half time lead through goals from Brian Talbot and Frank Stapleton.
 In the 86th minute, however, Gordon McQueen scored following a set-piece, and two minutes later Sammy McIlroy dribbled past two Arsenal players to score a dramatic equaliser.
 With the game poised for extra time, United's celebrations proved short-lived, as Alan Sunderland scored a last-minute winner, making the final result Arsenal 3–2 Manchester United.
 This match is often referred to as the "Five-minute Final". 2009 FA Cup Final
The 2009 FA Cup Final was the 128th final of the world's oldest domestic football cup competition, the FA Cup.
 The final was played at Wembley Stadium in London on 30 May 2009 and marked the third time that the final has been staged at the stadium since it was rebuilt.
 The match was contested by Chelsea, who beat Arsenal 2–1 in their semi-final, and Everton who beat Manchester United 4–2 on penalties after a 0–0 draw after extra time.
 After Louis Saha opened the scoring after just 25 seconds, the fastest ever goal in an FA Cup Final, Didier Drogba equalised in the 21st minute before Frank Lampard scored the winner with 19 minutes left to play to give Chelsea their fifth FA Cup success. 2012–13 Arsenal F.C. season
The 2012–13 season was Arsenal Football Club's 21st season in the Premier League and 93rd consecutive season in the top flight of English football.
 Arsenal participated in the Premier League and the UEFA Champions League, after finishing third in the previous Premier League season.
 The League Cup however was out of their reach, and despite an entertaining cup run, which included 13 goals scored in two games, Arsenal lost to fourth-division Bradford City in the quarter-finals on penalties.
 In the FA Cup, Arsenal were knocked out by Championship side Blackburn Rovers in the fifth round.
 The Champions League also proved fruitless, as despite a valiant effort in Bavaria winning 2–0, they were ultimately knocked out on the away goals rule against Bayern Munich, thus extending their trophy drought for an eighth season.
 The highest scoring game in their season was the famous 7–5 win in the League Cup (after extra time), where they came back from 4 goals down to beat Reading.
 Arsenal's highest scoring league win was the 7–3 win against Newcastle United in December.
 This season, Arsenal finished fourth after having to close another large points gap (like last season) between themselves and their North London rivals Tottenham Hotspur. 2014–15 Arsenal F.C. season
The 2014–15 season was Arsenal's 23rd season in the Premier League and 95th consecutive season in the top flight of English football.
 This season Arsenal participated in the Premier League, FA Cup, League Cup, Community Shield and the UEFA Champions League.
 An inconsistent start to the league season ended any realistic hopes for the Premier League title as Arsenal only won two out of their first eight games.
 Inconsistency plagued Arsenal throughout the first half of the campaign, not helped by numerous injuries to important players.
 At one stage, Arsenal were as low as eighth heading into early December.
 This would later haunt them as they mounted a superb recovery during the second half of the season where they won eight league games in a row, becoming the in-form side of the division.
 Ultimately, however, the gap between themselves and leaders Chelsea was too much, the points dropped during the inconsistent first half of the season proving too much to recover.
 Old habits were hard to eradicate in Europe as yet again, Arsenal were their own worst enemies.
 Despite being widely expected to reach the quarter-finals, having been given a favourable draw in the Round of 16 against AS Monaco, Arsenal self-destructed at home, where panic led to Monaco winning the first leg 1–3, a scoreline which ultimately proved fatal over the course of the tie.
 Arsenal, with their 0–2 away win proving useless, bowed out yet again in the round of sixteen for the fifth consecutive year.
 However, Arsenal reclaimed the FA Cup, thus becoming the most successful club in the history of the competition with twelve wins, comfortably beating Aston Villa 4–0 in the final.
 Arsenal finished the league season in third, thereby qualifying directly to Champions league group stage and avoiding the Champions League qualifier, something Arsène Wenger was keen to avoid as he felt it had a negative impact on competing for the Premier League title, which was the primary target set by the players, manager and coaching staff, going into the next season. 1998–99 Arsenal F.C. season
The 1998–99 season was the 101st season of competitive football played by Arsenal.
 The club, managed by Arsène Wenger, entered the campaign as Premier League and FA Cup double winners.
 They ended this campaign as league runners-up, a point behind Manchester United, who secured the title on the final day of the season.
 United also eliminated Arsenal in a FA Cup semi-final replay; Ryan Giggs scored an extra time winner in the 109th minute.
 Arsenal competed in Europe's premier club competition – the UEFA Champions League – for the first time since its rebrand in 1992, but failed to progress past the group stage. 2013–14 Arsenal F.C. season
The 2013–14 season was Arsenal Football Club's 22nd season in the Premier League and 94th consecutive season in the top flight of English football.
 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. 2015 FA Community Shield
The 2015 FA Community Shield (also known as the 2015 FA Community Shield supported by McDonald's for sponsorship reasons) was the 93rd FA Community Shield, an annual English football match played between the winners of the previous season's Premier League and FA Cup.
 The match was contested by Arsenal, the 2014–15 FA Cup winners, and Chelsea, champions of the 2014–15 Premier League.
 It was held at Wembley Stadium on 2 August 2015.
 Watched by a crowd of 85,437 and a television audience of over a million, Arsenal won the match 1–0. 2005 FA Cup Final
The 2005 FA Cup Final was a football match played between Arsenal and Manchester United on 21 May 2005 at the Millennium Stadium, Cardiff.
 It was the final match of the 2004–05 FA Cup, the 124th season of English football’s primary cup competition, the FA Cup.
 Arsenal became the first team to win the FA Cup via a penalty shoot-out, despite being outplayed throughout the game, after neither side managed to score in the initial 90 minutes or in 30 minutes of extra time.
 The shoot-out finished 5–4 to Arsenal, with Patrick Vieira scoring the winning penalty after Paul Scholes' shot was saved by Arsenal goalkeeper Jens Lehmann.
