Confederations Cup: Goal-line technology ready for use
BBC Sport looks at how goal-line technology will be used in the 2013 Confederations Cup in Brazil.
German-based manufacturer GoalControl will be used in Brazil over the next few weeks, and will continue at the World Cup in 2014.
Calls for the technology grew after Frank Lampard's goal was ruled out in England's 4-1 defeat by Germany in the 2010 World Cup.
