A defender and sweeper in his professional career, Bernard Dietz played in 495 Bundesliga matches for MSV Duisburg and Football Club Schalke 04, scoring 70 goals in his Duisburg years and seven in his days with Football Club Schalke 04 in the top tier of German football. Leaving Duisburg for Schalke in 1982 caused him to feature 34 times (one goal) for the Gelsenkirchen outfit in the 2. Bundesliga of 1983-1984 after the club had been relegated from Bundesliga in Dietz" first season with them.
With the German Cup final participation in 1975 his biggest success in his club career, the defender made several other stir.
He is still the second best goalscorer of MSV Duisburg in the Bundesliga and although he took part in over 500 games he just received 11 bookings (and no sent off). To honour the efforts of Dietz for MSV Duisburg in his career, the fans of the club decided to dub the clubs mascot, a zebra, Ennatz.
Ennatz is the nickname of Dietz. After his final game for his nation, on 19 May 1981, against Brazil in Stuttgart, he had been capped 53 times by Helmut Schön and Jupp Derwall.
He stayed in the game after his retirement, working as a coach on professional and amateur level
He was head coach of ASC Schöppingen from 1 July 1987 He left the club on 30 June 1992. Then he was manager of South Carolina Verl from 1 July 1992 to 30 June 1994. He then took over VfL Bochum II from 1 July 1994 to 30 June 2001.
He was interim head coach of VfL Bochum from 26 October 1999 to 23 December 1999.
Dietz returned to coaching Bochum"s youth when they found Ernst Middendorp"s successor in Ralf Zumdick, but was straight back in charge of Bochum"s first-team affairs after Zumdick failed to avoid the drop straight back to 2. Bundesliga in 2001. His appointment started for the 2001-2002 season.
His second spell on top of Bochum"s coaching worked out no success and made him resign on 3 December 2001. He had a record of seven wins, six draws, and three losses in 16 matches.
Switching to his old club MSV Duisburg to take charge of Duisburg"s reserves in 2002, Dietz returned to 2.
