The final was played only five weeks after the Hillsborough disaster, in which 96 Liverpool fans were killed in a crush, and before kick-off there was a minute's silence and the teams wore black armbands as a sign of respect.  Gerry Marsden, lead singer of Gerry & the Pacemakers, led the crowd in a rendition of his hit "You'll Never Walk Alone", which had become synonymous with Liverpool Football Club.

List of Sunderland A.F.C. seasons: 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.

BBC Goal of the Season: 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.
