Atletico Madrid file a complaint with UEFA after fireworks are set off outside the club’s hotel ahead of the Champions League semi-final second leg against Arsenal. Multiple reports say the disruption occurs late at night, affecting players’ sleep. According to accounts from Atletico sources, fireworks are heard on more than one occasion after 1am, with the noise occurring outside the hotel grounds. The complaint is presented to UEFA as Atletico seek acknowledgement and review of the circumstances surrounding the incident. The reports describe the episode as part of the build-up to the second leg, which follows the first meeting of the semi-final tie. Neither report indicates any direct link between the fireworks and match operations, but both frame the issue as one that interferes with the team’s preparation and rest. UEFA has not been described as issuing a response in the available reporting, and the sources do not provide details on who is responsible for setting off the fireworks.
