UEFA announced Wednesday that "semi-automated offside technology" will be used from the group stage of this season's Champions League as well as in next week's Super Cup. The optical tracking system was trialled at the FIFA Club World Cup in Abu Dhabi in February and last year's Arab Cup. FIFA have confirmed it will be in place for the World Cup in Qatar. The data-driven, limb-tracking technology utilises both dedicated and broadcast cameras around the stadium to give the exact position of players on the pitch, offering match officials precise information within seconds.
