Two systems, Hawk-Eye and GoalRef, were given the green-light by football's lawmakers on Thursday.

FIFA will introduce goal-line technology at the seven-team Club World Cup in Japan in December, and plans to use it in Brazil at the 2013 Confederations Cup and 2014 World Cup.

" I am happy, I am pleased we are able to go forward," he told Sky Sports NewsHD.

"When it comes to high level competition and a decisive moment, and you have the technology and don't use it - then something is wrong.

"This is a real, real approach of modern times in football, it is so important because the objective in football is to score goals.

"New tactics and techniques with so many players involved in attack it is difficult to score goals so now we have the chance to identify it then it is good."

Mind change

Blatter admitted he had changed his mind about goal-line technology after Frank Lampard's disallowed goal for England v Germany in the 2010 World Cup, and highlighted again after Ukraine were denied a goal against England in Euro 2012 despite the ball having crossed the line.

Blatter said: "For me as FIFA president it became evident the moment what happened in South Africa in 2010.

"I have to say 'thank you Lampard'. I was completely down in South Africa when I saw that it really shocked me, it took me a day to react.

"It happened again in Ukraine, and Ukraine can still not believe it now."

Blatter insisted, however, that there would be no move to introduce any video replays or other technology to rule on other decisions such as offsides, fouls or diving.
