Josef Emanuel Hubertus "Sepp" Piontek (born 5 March 1940) is a German former football player[1] and manager.

[3] After retiring he managed, in Germany, Werder Bremen (1971–1975), and later Fortuna Düsseldorf (1975–1976) and FC St. Pauli (1978–1979).

He sat through 115 international matches, leading Denmark to their first ever World Cup participation in the 1986 tournament.

He quit as Denmark coach in April 1990 after the Danish national team failed to qualify for 1990 FIFA World Cup, and later coached Turkey from an advice by fellow German and Piontek's teacher Jupp Derwall[4] from May 1990 to 1993, in which though failed to qualify for neither UEFA Euro 1992 nor 1994 FIFA World Cup, helped sparking a massive revival in Turkish football fortunes which would be witnessed by the time Piontek left.

[5] In the 1990s, Piontek returned to Denmark, where he coached Danish clubs Aalborg BK and Silkeborg IF, and subsequently worked with the Greenland national team.
