Atletico Madrid officials and players are said to be frustrated by fan behaviour, the refereeing appointments and a string of contentious moments that followed their Champions League exit

The night ended in frustration for Atletico Madrid as their Champions League campaign concluded with a 1-0 defeat at the Emirates. Behind the composed statements issued in public by coach Diego Simeone, Spanish reports say the club has been nursing private grievances about a series of events that unfolded before and during the tie.
Those concerns range from an intimidating reception outside their hotel to the selection of the match officials and several in-game decisions that Atletico feel were decisive.
Officially Simeone offered measured praise to his opponents — and refused to lean on excuses — but sources close to the squad describe a different tone inside the visiting delegation.
The mood was exacerbated by a post-match altercation in which the coach was reported to have pushed a club official at full-time, while medical staff and some players complained about how specific incidents were handled by referees and by the video assistant referee team.
What provoked Atletico’s grievances
Several factors combined to leave the club feeling aggrieved. First, there were the pregame scenes: supporters set off fireworks outside the team hotel and created a noisy welcome that unsettled staff and players. Secondly, the club objected to the appointment of the officiating lineup, notably referee Daniel Siebert and VAR lead Bastian Dankert, names that carry a particular history for Atletico when facing English opposition. Finally, specific match incidents — both physical challenges and time-wasting episodes — are cited as examples of how the encounter was tilted away from them.
Pregame disruption and security concerns
Atletico have reportedly considered a formal complaint to UEFA about the disturbance outside their hotel and the way the team’s travel was managed on matchday. Players and staff described feeling exposed for part of the journey to the stadium, with minimal escort amid loud scenes from home fans. The club’s unease over those events was amplified by memories of prior high-profile clashes and by the knowledge that the chosen match officials had previously overseen unfavourable results for Atletico when they visited England.
Contested decisions and the VAR debate
The refereeing appointments proved to be a flashpoint. Atletico sources were particularly unhappy about how three potential penalty situations were treated during the game and whether VAR was used to overturn or to review on-field calls. The club pointed to a pattern: similar names on the officiating teams had been present for recent exits from the competition and for defeats against English clubs, which fed a narrative of suspicion even before kick-off.
Three key penalty moments
The incidents Atletico cite include a tussle involving Riccardo Calafiori and Giuliano Simeone where a linesman flagged for offside and VAR was not asked to intervene, a separate contact on Giuliano that went unreviewed, and a moment when Calafiori appeared to step on Antoine Griezmann‘s foot in the penalty area after a saved shot. In that last case referees instead awarded a foul against Arsenal because of a different challenge in the build-up, a decision Atletico deemed particularly puzzling. Members of the squad shared images and clips on social platforms to highlight what they saw as missed opportunities for review.
Reactions, rhetoric and next steps
Publicly, Simeone struck a conciliatory tone: he congratulated Arsenal for progressing and commended their financial muscle and consistent approach. He insisted he did not want to make excuses, saying the team had given everything and that small margins had not fallen their way. Arsenal manager Mikel Arteta praised the referees, describing their performance as “very good”. Behind the scenes, though, Atletico remain said to be exploring whether to raise formal concerns with governing bodies about the match environment and the officiating choices.
Whatever the outcome of any complaint, the episode has already left its mark on relations between the clubs and on the narrative of the tie. For Atletico, the feeling is that a blend of intimidating atmosphere, controversial appointments and a handful of unexplained decisions combined to deny them a fairer chance to force extra time. For Arsenal, the victory and their fans’ celebrations concluded a tense two-legged duel — and the contrasting public responses from both managers ensured the story will be discussed long after the final whistle.
