Arsenal players expressed anger after referee Daniel Siebert blew the whistle before Bukayo Saka could take a corner during added time in their Champions League match against Paris-Saint Germain. The incident occurred while Arsenal were leading 1-0, with the team expecting to take the corner before the half-time break. Instead, Siebert ended the half prematurely, halting play while the corner was still pending.

Players and staff immediately protested the decision, visibly frustrated by what they perceived as a premature end to the half. The error denied Arsenal a potential opportunity to extend their lead just before the break, leading to strong reactions on the pitch. The moment has since drawn scrutiny over officiating consistency in high-stakes matches.
