Goal-line technology

Horne said there were eight or nine systems competing for licences and that all of them could prove successful in technology trials, with individual governing bodies then deciding which of them - if any - to use. "There's not going to be one technology for all of world football," he said. "There's a phase of testing up until March 2012 that will establish whether technology can actually achieve reasonable accuracy - 90 per cent, 99 per cent, maybe 100 per cent. "It's happening live in stadia all around Europe. They can simulate light, they can simulate dark, they can simulate balls rolling across the line, balls being fired in from all different angles." Horne also confirmed that the technology would only be used to establish whether or not a goal had been scored and not for decisions such as offside. "Those single points of scoring a goal are so vital and there are so few of them in a football match compared to tennis or cricket that that is where we need the technology," he said. "If you start using technology to judge offsides, for example, then I think you've gone too far."
