Explained: Why was the Julian Alvarez penalty ruled out in Champions League last-16?

The return leg of the UEFA Champions League round of 16 match between Atletico and Real Madrid ended in favour of the defending champion when Antonio Rudiger converted the decisive penalty in the shootout. Atletico Madrid’s Julian Alvarez scores a penalty during the penalty shootout wich is later disallowed after a VAR review for a double touch. In 2017, Leicester City forward Riyad Mahrez slipped during a penalty against Manchester City and his standing foot touched the ball before he converted the chance. “The referee said when Julian got to the penalty spot he touched the ball with his standing foot, but the ball did not move,” he said after the match. “So from a VAR perspective, they’re taking a look at not just a video, but as well as the touch points where semi-automated has about 26 different cameras looking at limb tracking technology, as well as a camera that’s on the ball in and of itself, which gives that VAR the ability to be more concise and direct and know when that ball was actually touched outside from the naked eye as well.” Former Republic of Ireland goalkeeper Shay Given said on BBC Match of the Day, “Sometimes you see it happen where the ball is kicked off the other foot and then goes in a completely different direction.
