Goal Line Technology?

The World Cup - the world's biggest sporting tournament (yes, it is bigger than the Olympic Games) has again been spoilt by some very poor refereeing decisions. Unnecessary or mistaken bookings cause problems to teams and heartache for the players concerned but the worst blunder was the disallowing of a goal scored by England in their defeat by Germany. The ball was well over the line and the match officials simply did not see it, whilst everybody else did. Referees will continue making these blunders until they are given proper help by FIFA in making the big decisions. 

I fail to understand why:

- the World's most popular game has only two referees assistants on the touchlines but not two more watching the goal line as well.
- the referee can consult the two referees assistants but cannot consult the fourth official, a qualified referee.
- the fourth official cannot view the video and then if necessary advise the match referee to stop the game and review what happened.
- There is opposition to goal-line technology, my least favoured option but still an acceptable one, if it works.

Tennis, for example, not only has has the Hawke-Eye line technology but it has an umpire, a referee, and umpteen line judges. Here are just three good reasons why football has been technologically left behind and why referees need help in getting the big decisions right:
