Chelsea to become first Premier League side to play with ‘robot-refs’ to make offside decisions at Club World Cup
The system uses up to 12 cameras in the stadium roof to capture the movement of all the players and the ball.
Up to 29 data points for each player, making up an animated skeleton, can be assessed 50 times per second to ensure decisions are correct.
If an attacking player is in an offside position, the tracking system alerts the VAR operator within half a second.
That message is then sent on to the referee, who is able to blow if he agrees the attacker was interfering with play.
The new system, which has been devised with the help of a number of tech companies, will end the painful, drawn-out process of waiting for lines to be calculated and drawn on screen.
It also would stop the current instructions to assistants not to flag instantly on “tight” offsides, which has been criticised for increasing the likelihood of injuries caused by desperate defenders.
