Chelsea midfielder Frank Lampard is proud of his role in bringing goal-line technology to the game.
His disallowed strike against Germany in the 2010 World Cup was the catalyst for this season's breakthrough.
"Bloemfontein was a particular moment, thank God it brought something good in end with the technology coming in," he said.
"But that's one of (the lows), that and missing a penalty and getting knocked out (of the 2006 World Cup) in Germany against Portugal. There's nothing worse than flying home when you've been knocked out of a tournament."
