TSV Schilksee is a German association football club from the Schilksee suburb of Kiel, Schleswig-Holstein. <SEP> 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. <SEP> Colchester United Football Club is an English professional football club based in Colchester, Essex, that was founded in 1937.

The club were relegated to the Fourth Division in 1961, but made an immediate return to the Third Division after finishing the 1961–62 season in second position, one point behind Millwall.  They bounced between the Third and Fourth divisions until 1990, when the club were relegated from the Football League for the first time in 40 years.  After two seasons in the Football Conference, the U's were promoted back to the Football League after winning the Conference title on goal difference over Wycombe Wanderers in 1992.  Colchester played in the Third Division between 1992 and 1998, when they won promotion to the Second Division after a play-off final win against Torquay United at Wembley.

The U's spent two seasons in the Championship, earning their highest-ever league finish of 10th position in the second tier before being relegated back to League One in 2008.
