football to the Bundesliga with a 2. Bundesliga title, followed up by SG Wattenscheid 09, who entered the Bundesliga for the first time. 1. FC Saarbrücken failed in the play-offs for a second consecutive time when it missed out to VfL Bochum, thereby ensuring a Bochum derby in the Bundesliga between VfL and Wattenscheid for the following season. In the relegation zone SpVgg Bayreuth failed to get reprieved for a third consecutive season and dropped into amateur football, as did Alemannia Aachen, a founding member of the 2. Bundesliga who had played all 16 seasons of the league until then. The tenth season of the single division 2. Bundesliga was to be the last in its current format for a time as the German reunification in 1991 lead to changes to the league after this season.
