Question: In 89th season of The Football League, which teams were in the FA Cup Final?

<P0-S0> Sunderland Association Football Club was founded in 1879 as Sunderland & District Teachers Association Football Club by James Allan. <P0-S1>  They turned professional in 1885. <P0-S2>  Sunderland won their first Football League championship in the 1891–92 season two years after joining the league. <P0-S3>  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. <P0-S4>  In the 1901–02 season, Sunderland won their fifth Football League First Division championship. <P0-S5>  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. <P0-S6>  The team's next success came in the 1935–36 season when they won the League Championship and also the Charity Shield. <P0-S7>  They had not won the FA Cup until the 1936–37 season when they defeated Preston North End in the 1937 FA Cup Final. <P0-S8>  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. <P0-S9>  Their next trophy came in the 1973 FA Cup Final as they beat Leeds United 1–0. <P0-S10>  They reached the 1985 Football League Cup Final but finished as runners-up to Norwich City after being beaten 1–0. <P0-S11>  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. <P0-S12>  Their first appearance in the Premier League came in the 1999–2000 season after being promoted as champions from Division One. <P0-S13>  In winning promotion the club gained 105 points, which was a record at the time. <P0-S14>  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. <SEP> <P1-S0> The 1988 FA Cup Final was the 107th final of the FA Cup. <P1-S1>  It took place on 14 May 1988 at Wembley Stadium and was contested between Wimbledon and Liverpool, the dominant English club side of the 1980s and newly crowned league champions. <SEP> <P2-S0> The 1987–1988 season was the 89th completed season of The Football League. <SEP> <P3-S0> The 2000–01 season was Port Vale's 89th season of football in the Football League, and first season back (thirty-eighth overall) in the Second Division. <P3-S1>  A season of two halves, Vale were struggling at the bottom of the table when Isthmian League minnows Canvey Island knocked the Vale out of the FA Cup with a 2–1 victory at Vale Park in 'one of the great shocks in FA Cup history'. <P3-S2>  They also exited the League Cup at the First Round. <P3-S3>  Things turned round in the second half of the season, as a twelve-game unbeaten run in the league was complimented with a League Trophy Final win over Brentford – the second time the club lifted the trophy. <P3-S4>  In the background of this was a financial crisis at the club, which motivated fan protests against Chairman Bill Bell.
