Rosenborg Ballklub is an association football club based in Trondheim, Norway.
 Twenty people have been manager of Rosenborg since 1965, when the position was created.
 Rosenborg reached the First Division (from 1992 the Norwegian Premier League) in 1967 and has played at that level ever since, except in 1978.
 Nils Arne Eggen is the club's longest-serving manager, having led the team for 22 seasons in five spurs between 1971 and 2010.
 He won the premiership in his inaugural season and has led the team for 14 of the club's 23 league-winning seasons.
 Eggen is also the one with the most matches as manager of Rosenborg with 729 matches, while Tor Røste Fossen and Jon Jönsson which is split second on the list only was in charge of the team for 89 matches.
 Erik Hamrén managed the team for 85 matches between 2008 and 2010, before he took over the Swedish national team.
 Per Joar Hansen, which lead the team for one season in 2006, has been the manager since 2013.
The 2007–08 season was Chelsea Football Club's 94th competitive season, 16th consecutive season in the Premier League, and 102nd year as a club.

 They will participate in Eliteserien, the Cup, Mesterfinalen and the 2017–18 UEFA Champions League, entering at the Second qualifying round stage.

Born in Battersea, Houseman signed professional terms with Chelsea in 1963, having played for the Chelsea Juniors.
 He made his debut for the club in the 1963–64 season in a 3–2 win over Sheffield United but made only sporadic appearances in his early years at Chelsea, with manager Tommy Docherty unconvinced by him.
 A section of the Chelsea crowd were also unconvinced by Houseman's performances, and he was often singled out for abuse throughout his time there.
 He featured in no more than twelve games per season in his first three years with Chelsea and missed out on the club's FA Cup final loss to Tottenham Hotspur in 1967.
Jørgen Skjelvik (born 5 July 1991) is a Norwegian footballer who plays for Rosenborg as a defender.
 After starting his career with the local club Stabæk, Skjelvik moved to Sweden where he played in Allsvenskan with Helsingborg and Kalmar, before he returned to Norway and joined Rosenborg in July 2013.
 He has represented Norway from under-18 to under-21 level, but was left out of the Norwegian squad for the 2013 UEFA European Under-21 Football Championship due to an injury.

 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.
