Aberdeen F.C.
Formed in 1903 as a result of the amalgamation of three clubs from Aberdeen, they rarely challenged for honours until the 1950s, when they won each of the major Scottish trophies under manager Dave Halliday. This level of success was surpassed in the 1980s, when, under the management of Alex Ferguson, they won three league titles, four Scottish Cups and a Scottish League Cup, alongside the European honours. Aberdeen were the last club outside of the Old Firm to win a league title, in 1984–85.
