Defenders in football have to keep a close eye on the foot movements of attacking players. When attempting to tackle a deft centre-forward, they need to anticipate where the ball is going to go in the next few milliseconds.
Today’s invention is intended to make the job of such players, especially at the highest level, even more challenging.
The studs on boots would each be fitted with a small LED. These could be made to switch on and off in patterns -so as to create extra, subtle shadows and suggest movement in a direction opposite to that in which the player’s weight is actually shifting.
The patterns could be made to vary, perhaps randomly, so that predicting the next body-swerve would be harder (and resulting in more goals).
