But Dattilo didn't send him off (there were no cards then, you either got sent off or you stayed on) and only awarded an indirect free-kick. The free kick did or did not go over the goal line. According to the Italian referee it did not.
Dattilo, an Italian and Italy was a contender to the Cup, just like England, was heard saying "Bono, bono" to Charlie Columbo after he had stopped Mortensen. Maybe the Americans thought "bono" was Italian for "good"?
The English had the best team in the world and probably the best player: Stanley Matthews. But Matthews was either slightly injured or the coach thought he could give him a day off for a match against the worst team of the World Cup and Matthews was even left behind in Rio.
The Americans give it all and they had a really good goal keeper. There were 14 clear shots on the American goal in the first half.
It was Joe Gaetjens, who was known to enjoy a few beers the night before a match, who took a 3,5 metres long dive to just slightly touch a shot that would have gone wide: 1-0.
