Prime Minister David Cameron has added his weight to the calls for goal-line technology following the controversy in England's World Cup defeat by Germany.
Sunday's 4-1 defeat in Bloemfontein saw the Three Lions crash out of the tournament at the last 16 stage.
England flattered to deceive in their worst-ever World Cup finals defeat, but the match will be remembered for the referee and his assistant failing to spot that a shot from Frank Lampard had crashed down off the underside of the bar and landed comfortably over the line with the score at 2-1 late in the first half.
"I do think that the use of technology in sport can be a bonus," said Cameron from the G20 summit in Toronto.
"I'm a keen follower of cricket and tennis and I think the third umpire has been a great thing and the machines that bleep at Wimbledon are quite handy too.
"Maybe that's something that football could now have a look at."
Cameron watched the second half of the match with German Chancellor Angela Merkel and afterwards spoke of his disappointment at the defeat.
"Everyone in the country will be disappointed with the result, but these things happen," he said.
"At least with a scoreline like that we can't say we were robbed. We weren't. We were beaten."
