Goal-line technology: Famous 'ghost goals' in pictures

- Goal-line technology has been given the go-ahead by football's governing body, Fifa. It's after a series of "ghost goals" like Frank Lampard's against Germany in the 2010 World Cup in South Africa. The strike was ruled out despite clearly crossing the line with Germany leading 2-1.
- One of the famous debates over whether a ball had gone over the line in a football match also involved an England v Germany match. With the 1966 World Cup final in extra time, striker Geoff Hurst scored with a controversial goal that bounced off the bar and back into play. It stood and England won the trophy.
- At the recent Euro 2012 tournament in Ukraine and Poland, John Terry appeared to kick a ball off the line in England's group match against Ukraine. Replays showed it had crossed the line. After months of testing, the International FA Board (IFAB) is now set to approve both the Hawk-Eye and the GoalRef systems.
- That decision will give the green light to the Premier League and Football Association to introduce the technology. Another famous goal that was ruled out was a Pedro Mendes effort for Tottenham against Manchester United in 2005. Replays showed it had clearly crossed the line.
- There will still be a delay before either system can be used in competitive football however. Each will need to be licensed, installed and then tested in every venue to make sure it is working properly. Frank Lampard's goal against Tottenham (pictured) stood in 2011 despite not appearing to cross the line.
- Another goal that should not have stood was "scored" by Reading against Watford in the 2008 Championship play-off final. The referee and his assistant awarded a goal despite the ball crossing the line metres outside the goal post. None of the Reading players even appealed for a goal to be given.
- Another example of a disallowed goal involved a title decider between AC Milan and Juventus in Italy last season. Sulley Muntari's goal wasn't given and Juventus went on to equalise and eventually win the Serie A title. The IFAB will insist that goal-line technology is only used to help referees make a decision.
