Really? In Northern Europe I think this is seen - perhaps hypocritically - as poor sportsmanship.
honestly the germans in football are not known for their sportsmanship (Especially when talking about guys like Harold Schumacher, Stefan Effenberg Or professional divers like Andreas Moller and Jurgen Klinsmann (this self-declared)
even the most "nice guys" like Rummenigge, lothar Matthaus they are a bit arrogant
Incredibly despite the reputation of being cold,on football in the past the Germans had several hot-headed players, especially in the 80s and 90s, bernd Schuster, Harold Schumacher, Stefan Effenberg, Oliver Kahn, Carsten Jancker, Mario basler and others All known for their temperament on and off the field, one example is bernd Schuster One of the best midfielders (Played for Barcelona and Real Madrid) of the 80's but didn't make it to any World cup due to infighting in the national team with others players, Or Effenberg who in the 1994 world cup gave the middle finger to the German fans and never went to any world cup again (1998 and 2002) also never participated in any competition with Germany again (euro 96, 2000 and World cup 1998 2002),
Klinsmann himself was not someone easy to deal with either, I remember a game in which he was substituted playing for Bayern and he had a tantrum, even hitting An object in the field, From the 2000s this type of German player disappeared
