Technology to be used at World Cup
FIFA has approved the use of goal-line technology for the 2014 World Cup in Brazil.
It will also be used at the Confederations Cup, which takes place in the country from June 15 this year, the governing body said.
A statement on the FIFA website read: "After a successful implementation of Goal-Line Technology (GLT) at the FIFA Club World Cup in Japan in December 2012, FIFA has decided to use GLT at the FIFA Confederations Cup Brazil 2013 and 2014 FIFA World Cup Brazil.
"The aim is to use GLT in order to support the match officials and to install a system in all stadia, pending the successful installation, and pre-match referee tests."
FIFA has launched a tender and is inviting goal-line technology providers to apply to supply the systems, with the final decision on the provider to be made in April. Hawk-Eye and GoalRef both have FIFA approval, with the former using cameras and the latter involving a low-frequency magnetic field surrounding the goal and an electronic circuit in the ball.
Goal-line technology has been the subject of debate for several years. England famously scored against West Germany in the 1966 World Cup final when Geoff Hurst's shot cannoned down from the crossbar, while England were denied an equaliser in their second-round defeat to Germany at the 2010 World Cup when the officials failed to spot that Frank Lampard's effort had crossed the line.
At the 1986 World Cup, Spain lost 1-0 to Brazil in their opening match due to the failure to award a goal to Michel in similar circumstances.
Despite widespread support for the use of goal-line technology, UEFA president Michel Platini has repeatedly stated his opposition. In December, in light of the trials at the Club World Cup, he had said it was an unnecessary expense.
"I prefer to give €50 million to grassroots than goal-line technology for perhaps one or two goals a year," he said then. "If the goal-line referee is one metre from the line and he has good glasses, he can see whether the ball is inside or not."
He has also expressed the view that technology should not be introduced until it can cover all aspects of the game.
At the 2012 European Championship, the officials had failed to spot that Marko Devic's shot had crossed the line before being cleared by John Terry in a match between Ukraine and England, yet there had been an offside in the build-up.
"The goal between England and Ukraine: it was a goal," Platini said in June. "It was a mistake from the referee, but there was an offside before then. If the officials had given offside there wouldn't have been a goal, so why don't we have technology for offside decisions as well? Where does it stop?"
He added: "If tomorrow someone handballs it on the line and the referee doesn't see it, what then? We can't just have goal-line technology. We also need sensors to see if someone has handballed it. We need cameras to see if it should be a goal or not."
