One controversy concerns the 2–2 equaliser. Hungarian goalie Gyula Grosics jumped to catch Fritz Walter's corner shot, but Hans Schäfer obstructed him (in plain sight of TV cameras), allowing the ball to reach Rahn, who then scored. Another controversy concerns allegations of doping. Though teammates steadfastly denied this rumour, German historian Guido Knopp claimed in a 2004 documentary for German public channel ZDF that the players were injected with shots of vitamin C at half-time, using a needle earlier taken from a Soviet sports doctor. This would explain both the better condition of the West German team in the second half and the wave of jaundice among their players following the tournament. A Leipzig University study in 2010 posited that the West German players had been injected with the banned substance methamphetamine.
