However, the season was overshadowed by the first great conflict of Weisweiler with his star. Günter Netzer was, with teammates Herbert Wimmer and Jupp Heynckes, part of the powerful German side that won the 1972 European Championship in Belgium. Many thought he was the tournament's most glamorous player. Weisweiler may have resented that he himself was no longer the star of the team. Netzer may have wanted to move to a more glamorous club, that paid him more. The conflict ended in separation, and a few weeks before the end of the season Netzer's departure to Real Madrid was announced. There was still one important match to go: the DFB-Pokal cup final in Düsseldorf, against Weisweiler's original club 1. FC Köln. The atmosphere was emotionally charged, made more so because the coach left Netzer on the bench. The match unfolded into one of the greatest West German cup finals. Despite a temperature of 35° both teams played attacking football, and on both sides the goalkeepers, Borussia's Wolfgang Kleff and Cologne's Gerhard Welz, were called on to make great saves. Welz even saving a second half penalty by Heynckes. In the short break before extra time Netzer removed his track suit and, it is said, told Weisweiler he would be playing. Shortly after the game resumed, Netzer, with only his second possession of the ball, scored a stunning, unforgettable winner for Borussia after a give-and-go with Bonhof. Thus ended one of the 1970s great coach-player associations, with Weisweiler and Netzer, in their last year together with Borussia, winning the DFB-Pokal cup but only finishing fifth in the league.
