Career
In 1969, Football Club Schalke 04 paid Football Club Schwelm 06 38,000 Deutsche Mark to sign promising stopper Rüssmann, who did not enjoy the best of starts at the Gelsenkirchen-based outfit under Rudi Gutendorf, but then gained more regular appearances for the club and seemed destined for a successful career. Initially Rüssmann (among other Schalke players) had controverted those claims. Rüssmann was one of the crop of players that committed perjury in the affair and got, as a consequence, punished with a fine by a court in 1975.
In 1973 (and shortly in the course of the 1976-1977 season), Rüssmann was banned temporarily from club action by the German Football Association, but given the allowance for appearances in foreign leagues.
So he left Football Club Schalke 04 in 1973 to see out his Bundesliga ban with Belgian outfit Club Brugge (11 matches, 0 goals). Returning to Schalke afterwards, Rüssmann stayed on with the club until December 1980.
Before the 2015/15 season only 23 players had amassed more appearances in the Bundesliga than Rüssmann. A respected youth international for West Germany, Rüssmann was already on the verge of a West Germany debut in 1971, but then saw his hopes ruined by his role in the match fixing Bundesligaskandal.
He came to action in all six matches, but after their (early) elimination he did feature just one more time for his nation in the rest of his career.
In 1987, Rüssmann returned to Football Club Schalke 04 as an off-pitch authority and was general-manager of the club from 25 February to 10 August 1987. With Borussia Mönchengladbach"s veteran general-manager Helmut Grashoff looking for a successor, Rüssmann started to work as assistant to Grashoff at Mönchengladbach in April 1990 and got Grashoff"s replacement later on. On 8 July 1992, Rüssmann was sacked by Mönchengladbach, but re-appointed by the club in September 1992 due to a change of view inside the Mönchengladbach presidium.
On 10 November 1998, Rüssmann was finally out of the door at Mönchengladbach following a complete change of environment caused by an ongoing disastrous run of results in the Bundesliga since 1996.
From 1 February 2001, Rüssmann was general-manager of Bundesliga side VfB Stuttgart, getting the sack by Die Schwaben in December 2002. He died on 2 October 2009 from prostate cancer less than two weeks before he would have turned 59.
