In the following season 1978–79 Udo Lattek managed Borussia for the last time. Many regulars left the club, such as the later vice-president Rainer Bonhof, or announced their career end, such as Jupp Heynckes and Berti Vogts. Lattek did not succeed in offsetting these departures with appropriate new signings. On Matchday 30, the team was in 15th place with a goal-difference of 38:47 goals: three wins from the last four games improved the finish to tenth place. It was the first season in a long time in which the club finished with a negative goal-difference. Borussia signed Jupp Heynckes to be assistant coach to Lattek this season. The second international title started on 9 May 1979. The first leg in the UEFA Cup against Red Star Belgrade ended in a draw. In the second leg on 23 May 1979 Borussia won 1–0 at home to win the UEFA Cup for the second time.
