Immediately after the 1954 FIFA World Cup Final, rumors emerged that the West German team had taken performance-enhancing substances. Several members of the team fell ill with jaundice, presumably from a contaminated needle. Members of the team later claimed they had been injected with glucose, and the team physician Franz Loogen said in 2004 that the players had only been given Vitamin C before the game. A Leipzig University study in 2010 posited that the West German players had been injected with the banned substance methamphetamine.
