New Introductions: Goal-Line Technology and Vanishing Spray

This year's tournament has seen the introduction of two new ideas into the International game; goal-line technology and a favourite of mine, vanishing spray. the idea behind them is to obviously assist the match referees deal with debatable issues and to prevent players from encroaching when defending free-kicks or moving the ball after the referee measures out 10 yards.

Vanishing spray, bring it to English football?

Goal-line technology has been a topic that has been discussed for years now as something that needs to be brought into the game somehow. In fact had it been in use during the last World Cup in South Africa, England would have rightfully been helped by it with Frank Lampard's 'goal', and who knows how the defeat to Germany would have panned out as a result. It has actually been used in England briefly in recent times, but not in a major tournament before now.
The system that is being used in Brazil is called GoalControl, a collection of 7 high-speed cameras per goal. These cameras track the flight of the ball and ultimately detect whether or not the the ball has crossed the line, before sending a message to the referee's watch, almost like a notification on your phone. It is a simple enough process in my eyes and has shown in this World Cup to be effective. In the group match between France and Honduras, a goal was given correctly to France via the use of GoalControl. The on screen video showed that the ball hadn't originally crossed the line after the shot hit the post, but after hitting the Honduras goalkeeper it did in fact go over the line.
in terms of being the future of football, I'm all for it personally. It doesn't take any time to make the decision (it takes less than a second to notify the referee) and helps to get the correct result. Other sports have successfully introduced technology; rugby, tennis and cricket for example, so why not gradually introduce it into professional standards of football on a greater scale than just major competitions?

The vanishing spray is a brilliant idea in my opinion. As someone who takes free-kicks for my teams when I play, I personally get frustrated when you can see opposition players coming closer than they should be and ultimately making it harder for you. So for me the idea is fantastic as it enables the free-kick to be as advantageous to you as it is meant to be.
The spray itself is made up mainly of water and butane gas in an aerosol can, with the butane gas expanding when the pressure is changed during the spraying action. The substance we see on the pitch is butane 'droplets' that are covered in water, with the butane eventually evaporating.
Future of football? Definitely. The idea is so simple that it is surprising that it hasn't been used in major tournaments before. It also is easy enough for the referee to have a can strapped to their waist for the game, and shouldn't be an expensive process. Reportedly the vanishing spray is going to be used in the Champions League next season, and is being considered by the Premier League, which just shows the impact that it has had.

I have been very impressed by these new introductions, they are certainly beneficial to matches and I think that many seem to have the same opinion. The next step that is needed is to integrate them into more competitions, not just the World Cup.
