Three players in the German football team beaten by England in the 1966 World Cup final had taken stimulant drugs, it has been reported.
Historians from Berlin's Humboldt University have discovered a letter that suggests three players from the West German side had tested positive for ephedrine. The drug is used in cold medicine but is also as a stimulant.
The letter, seen by German newspaper Der Speigel, was sent by the chairman of Fifa's medical committee at the time, Yugoslav Mihailo Andrejevic, to fellow doctor Max Danz, president of the West German Athletics Federation.
1966 was the first year that players were forced to undergo tests for doping and the teams were issued with a list of drugs that were banned.
Fortunately for England the banned substances were not quite performance enhancing enough, as Alf Ramsey's side won the game 4 -2 and lifted the cup.
