Ex-Holland star Johnny Rep has admitted to the dive which helped to eliminate Scotland from the 1978 World Cup.
Scotland beat Holland 3-2 in 1978
Scotland needed to defeat the Dutch by three goals but fell short, winning a famous match 3-2 in Mendoza, Argentina.
In a new book '78: How a Nation Lost the World Cup', Rep said: "I dare to admit now, that after half-an-hour I committed a schwalbe (a show - a dive).
"This action caused a penalty-kick from which Rob Rensenbrink scored to make it 1-0."
After defeat by Peru and a draw with Iran, Scotland had suffered a disastrous start to the campaign under manager Ally McLeod.
And the slim chance of progressing was dented when, after a Kenny Dalglish strike had been ruled offside, Rep went to ground.
The Scots fought back heroically and, following Archie Gemmill's sublime strike, they led 3-1 before Rep himself struck from long range.
Holland went on to reach the World Cup final where they were beaten by 3-1 hosts Argentina in extra time.
