http://www.bbc.com/sport/football/35736241 A trial of the use of video assistant referees for "game-changing decisions" in football will begin no later than the 2017-18 season. The news was confirmed following a meeting of the International Football Association Board (IFAB) in Cardiff. Technology would only be applied to key incidents concerning goals, red cards, mistaken identities and penalties. IFAB say they have had interest in hosting live trials from 12 national associations and one confederation. The new Fifa president Gianni Infantino, who believes greater use of technology within the game is inevitable, called it an "historic" day for the sport and said the decision proved they were "listening to football" over its concerns. IFAB insist that a final decision on approving the technology for use throughout football will only be made following a thorough period of testing and an agreement on the protocols for its use. Infantino said: "We cannot close our eyes to the future but it doesn't mean to say it will work. "The flow of the game is crucial. We cannot put that in danger. That is why we have to be open to test."
They also need the same goaline technology we're using now set up at the corner flags. It's instant response, no reason it can't be used for the ball going out of play.
It would work through the same sensor the Ref has for the goal line. The alert would be instant. The less the dozy officials have to do with decision making the better.
Use of technology is a must - so much money attached to results means football has to evolve (like other sports using technology) but it will need to be secure technology or corrution will creep in - money & fraud go hand in hand
