How much technology does football need?

IFA president Sepp Blatter last month repeated his pledge to have goal-line technology in place for the 2014 World Cup.
And a report in today’s Daily Mail suggests the world governing body are days away from making a statement about technology in the game with Hawk-Eye in talks with the world governing body.

The company, who provide a similar service in cricket and in tennis, would use a six-camera system to determine whether the ball has crossed the line.

Critics say technology will slow the game down, that the margin for error remains too large and it would mean different rules for different competitions.
However, advocates of technology say the price of making a mistake in modern football is just too high.

Meanwhile a new high-tech ball that can also show when the ball is received in an offside position or when it goes out of play for a throw-in or a corner is being developed.

So what you do think? Should goal line technology be introduced and should it be extended to other areas of the games?
