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.
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.
In English football, the Goal of the Season is an annual competition and award given on BBC's "Match of the Day", in honour of the most spectacular goal scored that season.
 It is typically contested between the winners of the preceding ten Goals of the Month, although the goal can and has come from any game in the regular season, including international qualifiers and friendlies—potentially from the opening league games of the season to the end of the European season UEFA Champions League final.
 In several instances, the goal has come in the final game of the domestic season, the FA Cup Final, the most recent example of which is Steven Gerrard's last minute goal in 2006.
 However, in 1980-81 for example the superb goal scored by Ricky Villa in the FA Cup Final replay for Tottenham Hotspur against Manchester City could not be considered as voting had already taken place.
The 2008 FA Cup Final was a football match held at Wembley Stadium on 17 May 2008 and was the final match of the 2007–08 FA Cup competition.
 The match was the 127th FA Cup Final, and the second to be held at the new Wembley Stadium since its redevelopment.
 The match was contested by Portsmouth and Cardiff City, with Portsmouth winning 1–0.
 This was the first time that the two sides have ever met in the competition.
 Both teams were aiming to win the FA Cup for the second time, Cardiff having won it in 1927 and Portsmouth in 1939.
 Had Cardiff won, they would have been the first club from outside the top division of English football to have won the competition since West Ham United in 1980.
 The match had an attendance of 89,874, a record which still stands as the largest ever for an FA Cup Final at the new Wembley Stadium.
The 2015 FA Cup Final was the 134th final of the FA Cup, the world's oldest football cup competition.
 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.
The 2015 FA Women's Cup Final was the 45th final of the FA Women's Cup, England's primary cup competition for Harshavardhan women's football teams.
 The showpiece event was the 22nd to be played directly under the auspices of the Football Association (FA) and was named the SSE Women's FA Cup Final for sponsorship reasons.
 The final was contested between Chelsea Ladies and Notts County Ladies on 1 August 2015 at Wembley Stadium in London.
 Chelsea made its second final appearance, after losing the 2012 final.
 Notts County appeared in its first ever final.
Sunderland Association Football Club was founded in 1879 as Sunderland & District Teachers Association Football Club by James Allan.
 They turned professional in 1885.
 Sunderland won their first Football League championship in the 1891–92 season two years after joining the league.
 They won the next Football League First Division on three occasions in four seasons; in 1892, 1893 and 1895, separated by a runner-up spot in 1894.
 In the 1901–02 season, Sunderland won their fifth Football League First Division championship.
 They came close to completing the "league and cup double" in the 1912–13 season, winning the league but losing to Aston Villa in the 1913 FA Cup Final.
 The team's next success came in the 1935–36 season when they won the League Championship and also the Charity Shield.
 They had not won the FA Cup until the 1936–37 season when they defeated Preston North End in the 1937 FA Cup Final.
 Sunderland entered The Football League in 1890 and were not relegated from the top division until the 1957–58 season; a total of 58 seasons in the highest division of England.
 Their next trophy came in the 1973 FA Cup Final as they beat Leeds United 1–0.
 They reached the 1985 Football League Cup Final but finished as runners-up to Norwich City after being beaten 1–0.
 In the 1986–87 season Sunderland were relegated to the Football League Third Division for the first time in their history under the management of Lawrie McMenemy, they however, returned to the second division the following season as champions–their lowest position in the English football league system.
 Their first appearance in the Premier League came in the 1999–2000 season after being promoted as champions from Division One.
 In winning promotion the club gained 105 points, which was a record at the time.
 Sunderland gained just 15 points in the 2005-06 season, which set the record for the lowest number of points in a Premier League season, which has since been eclipsed by Derby County.
The 1895 FA Cup Final was contested by Aston Villa and West Bromwich Albion at Crystal Palace.
 Aston Villa won 1–0, with Bob Chatt being credited with scoring the fastest goal in FA Cup Final history, scored after just 30 seconds.
 This record would stand for 114 years before being broken by Louis Saha of Everton in the 2009 FA Cup Final with a goal after 25 seconds.
The 2013 FA Cup Final was the 132nd final of the FA Cup, the world's oldest football cup competition.
 The match, contested by Manchester City and Wigan Athletic, took place on 11 May 2013 at Wembley Stadium in London, and kicked off at 5:15 p.m.
 It was Wigan's first FA Cup final and Manchester City's 10th.
 Wigan pulled off a shock victory against favourites City, winning in circumstances reminiscent of the 1988 FA Cup Final when Wimbledon overcame Liverpool.
 Ben Watson's stoppage-time headed goal produced the "greatest FA Cup Final upset for a quarter of a century".
 In the United Kingdom, the match was televised by ITV and ESPN.
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.
