Eleven seconds: the fastest goal in World Cup history

Hakan Şükür scored after 10.8 seconds against South Korea in the 2002 third-place match, the fastest goal ever netted at a World Cup.
The fastest goal in World Cup history arrived almost before fans had settled into their seats. It was scored by Turkey's Hakan Şükür after 10.8 seconds — usually rounded to eleven — in the 2002 World Cup third-place match.
It was 29 June 2002, in Daegu, against hosts South Korea. Turkey eventually won 3-2 and sealed the best World Cup in their history with that third place, built on a lightning strike straight from kick-off.
Şükür's record dethroned a mark that had stood for forty years: that of Czechoslovakia's Václav Mašek, who had scored after 16 seconds against Mexico at the 1962 World Cup.
Among the most famous early goals is also that of England's Bryan Robson, who opened the scoring against France after 27 seconds in 1982 (England won 3-1) at San Mamés. But none has gone below Şükür's mark, still unbeaten.
