Brøndby IF

Formation (1964–1977)

Brøndbyernes Idrætsforening was formed on 3 December 1964 following a merger between two local rivals – Brøndbyøster IF and Brøndbyvester IF. The merger was to be completed as a prerequisite for the construction of a new stadium by Brøndby Municipality. Brøndby IF spent its inaugural season as an amateur club in the 6th tier of the 11 Danish leagues, the Serie 1, where they finished their two first seasons in fourth place. Among the players of the early years was team captain Per Bjerregaard, a doctor who had moved to Copenhagen from Randers in Jutland, and Hans Gregersen, who was the mascot of the team until his death by syphilis in 1967. In 1967, the club hired coach Leif Andersen who instantly secured promotion to Sjællandsserien (the Zealand series). After a few mediocre years, a new coach, John Sinding, was brought in, and the club won promotion to Danmarksserien (the Denmark series).

In 1973, Per Bjerregaard stopped his active career at 27 years of age and became chairman of Brøndby; his first action was to sack head coach Sinding. In his place, Brøndby hired former professional and Denmark national team player Finn Laudrup, who took over as head coach while he still took actively part in the matches as a player. Laudrup joined his brother-in-law Ebbe Skovdahl in the Brøndby team, and he brought his two young sons Brian and Michael Laudrup with him to the club. Under Finn Laudrup's influence, the club's playing style was changed to a more attacking strategy, even though Laudrup decided to fully concentrate his efforts as a player after only a year. After winning promotion in 1974, Laudrup left Brøndby in the third Division in 1976 to play for KB in the Danish top-flight league (then named the 1st Division) and a year later Michael Laudrup, the brightest talent in Danish football, followed.

Professional football (1977–1987)

In 1977, Brøndby moved up into the second Division, and were one of the clubs who quickly adapted to the new times of paid football in the best Danish leagues in 1978. Per Bjerregaard persuaded Finn Laudrup into returning to Brøndby in 1981 on a professional contract, and following a season of 85 goals in 30 matches, Brøndby won promotion to the top-flight 1st Division under coach Tom Køhlert. Finn Laudrup subsequently ended his career at age 36, but in his place Michael Laudrup returned for the 1982 season, being one of ten players leaving KB that year.

Brøndby won their 1st Division debut match 7–1 over fellow promoted team B 1909 in a match which featured two goals from Michael Laudrup. He was subsequently called up for the Denmark national team, and on 15 June 1982 he became the first Brøndby player to win a cap for the national team. Brøndby finished their first 1st Division season in fourth place with Laudrup the league's third top goal scorer with 15 goals, earning him the Danish Player of the Year award. In 1983, Laudrup was sold to Juventus in the then-biggest transfer deal in Denmark, giving Brøndby the economic foundation to expand further.
