The disallowed goal by Lamine Yamal has reopened the debate about the reliability of the SAOT system, the semi-automatic offside technology that determines whether a player is in an illegal position. This tool has been implemented in La Liga since the 2024-25 season and represents a significant improvement over the previous system, in which referees manually drew the lines. The system is called semi-automatic because it requires human intervention to resolve the play. The role of the VAR official is to determine the exact moment when the striker's teammate last touches the ball. From there, the program calculates whether the position is legal. In certain situations, the referee can choose between one or two options. framesSince slow-motion images make it difficult to establish with absolute precision when the ball last touches the player's foot, referees never know in advance how the play will unfold. To expedite the process and increase reliability, the ball would need to incorporate an official chip that would allow the exact moment of the last touch to be determined. However, La Liga rejected this option for economic reasons, as well as the implementation of a clock that alerts the referee when the ball has completely crossed the goal line in cases of phantom goals. A headache for the CTA (Technical Committee of Referees).

Hawk-Eye, the company responsible for the semi-automatic offside system, provides the broadcast team with a graphic representation to justify the VAR decision. The problem is that the shortcomings of this simulation raise more questions than answers: the mannequins are all the same height, wear the same shoes, and lack features like hair, which detracts from the image's realism. One of the most surreal representations occurred during last season's Real Sociedad-Barcelona match, when Robert Lewandowski's disproportionately large foot was shown to justify an offside call. This Sunday, also at Anoeta, an image was circulated showing Lamine Yamal perfectly aligned with the defender, but a second test had to be sent out, revealing that part of his heel was slightly forward.

There had always been suspicions about Real Madrid's pressures on the Spanish Federation (RFEF) over refereeing, but until now they had not come to light. Beyond public statements of protest, after a specific match where controversial calls had been made, no details of what was happening behind the scenes was known. However, 'El Confidencial' has published some of the messages Sergio Ramos, when captain of Real Madrid, sent RFEF president Luis Rubiales in order to complain about the refereeing and tell him openly that they favoured Barça.
