il Var, Video assistant referee, is refined and enriched. At the Arab Cup in Qatar at the start on November 30, a luxury starter for next year’s World Cup, one is making its debut technology designed for support the linesmen in offside decisions. This is the most important experiment carried out so far on a point that has always been enormously controversial in the regulation and which, up to now in the competitions in which it is operational, was indeed dealt with with the traditional Var, like all other game infringements.
It was to intervene on the point Pierluigi Collina, president of the FIFA referees commission since 2017, who in an attempt to reassure the “human” contribution to the evaluations explained how “in the event of an offside, the decision is made after analyzing not only the position of the players but also their involvement in the movement. Technology – today or tomorrow – can draw a line but the evaluation of interference with the game or with an opponent remains in the hands of the referee “. To go into more detail, always on the official Fifa channels, was instead Johannes Holzmüller, Football technology & innovation director of the federation: “We will have a camera system installed under the roof of each stadium. The limb tracking data extracted from the video will be sent to the operations rooms and the offside line calculated as well as the crossing point detected they are provided to the replay operator in near real time. ”At that point the replay operator can immediately submit that fragment to the referees sitting at the Var: at the Arab Cup there will be a Var assistant dedicated exclusively to offside. inform the referee on the field of what the images will have established.
According to Bbc semi-automated system collects data from 29 parameters for 50 times per second and for each player. The cameras mounted on the roofs of the plants will be between 10 and 12 and obviously the new system dedicated to offside should be more than that faster – with the benefit of the pace of the game – but also more precise compared to the current configuration of the Var. If this further experimentation – after those in England, Spain and Germany – gives satisfactory results, this “specialized Var” could also be used for World Cup matches.
Mourinho after Roma-Bodo: “Referees always make mistakes against us”
Fifa and Ifab, the International Football Association Board which has the authority to decide on the regulation at the international level, are meanwhile continuing to study a possible change to offside that puts an end to the often millimeter calls that are the result of the Var and the cancellations of goals on truly negligible measures compared to the positions of the head, body, legs and feet: the hypothesis is to return to the old, with the need to raise the flag is necessary “light” between the bodies, that is an empty space between the penultimate defender and the attacking player, and to consider only the position of the lower limbs, thus excluding the upper part of the body.
