After the club had twice finished in previous years third place in the table, coached Hennes Weisweiler in the 1969–70 season especially the defence. Deviating from the "foal" concept, Borussia bought for the first time experienced defensive players like Luggi Müller and Klaus-Dieter Sieloff. With Ulrik le Fevre the club signed their first Danish player, later followed by Henning Jensen and Allan Simonsen. This season saw the first Bundesliga victory over Bayern. After a 5–1 win over Alemannia Aachen on 31 October 1969, Borussia topped the Bundesliga for the first time. Today (as of December 2018) Borussia takes third place in the list of league leaders in the Bundesliga behind Bayern and Dortmund.
