The main purpose of the verification report by the Atlético Supporters’ Union (Unión ATM) is to demonstrate that the video evidence provided by UEFA contains editing traces sufficient to affect factual judgments, and therefore, in terms of credibility and legal effectiveness, cannot be regarded as reliable 'objective evidence.' It should be emphasized that the report does not directly address the controversy over whether VAR should intervene or why referees can make crucial decisions within seconds, but instead focuses on the credibility of the video evidence provided by UEFA itself.
The two most convincing parts of the report are, first, the information-entropy analysis (page 25), and second, the CMFD (copy-move forgery detection) heatmap (page 31, see screenshot). Especially the second point: in naturally shot videos, it is impossible for large areas of human pixels to have identical cloned regions; this is a typical feature of videos that have undergone post-processing.
In fact, prior to this report, several analyses (including hints from Marca) suggested that the video had been tampered with. When discussing this with friends in Madrid at the time, we also mentioned that in the era of multi-angle, high-definition broadcasts of the Champions League, the low-resolution, poor-quality, strangely-angled video that UEFA used to prove that the referee's decision was 'correct' not only had severe frame drops between actions, but the ball's movement showed no spin, which is physically impossible. Álvarez's 'action' looked more like a still-frame displacement rather than real video footage, which has now been technically proven. At the end of the report, Unión ATM explicitly requested UEFA to release the unedited original video and stated that it would seek accountability through civil legal means, which is also a pressure tactic commonly used in similar cases.
To emphasize again, the core of this report is not whether Álvarez truly 'touched twice,' nor is it about the specific application of the rules, but rather about the challenge to UEFA's credibility and procedural justice.
