Atlético Madrid's Anger After Champions League Defeat
The final whistle at the Emirates did not end Atlético Madrid’s anger. It simply moved it to a different arena.
Within hours of the Champions League semi-final defeat, Giuliano Simeone opened up a fresh front on Instagram, posting a furious critique of the officiating that he clearly felt had tilted the tie Arsenal’s way.
The 21-year-old forward shared two screenshots from the match, zeroing in on a flashpoint that had barely registered during live play but has since become a rallying image for Atlético fans. In the stills, Simeone is seen sprinting towards the ball before being shoved to the turf inside the Arsenal penalty area by left-back Riccardo Calafiori, with the winger seemingly well placed to challenge for a loose ball.
On the night, the assistant’s flag went up. Offside. End of story. No penalty check, no VAR monitor, no delay.
Simeone’s screenshots tell a different version. The images suggest he may have been inside his own half when Jan Oblak launched the long ball over the top – a crucial detail, because a player cannot be offside in his own half. If that interpretation is correct, the offside call was wrong, the shove should have been examined as a potential penalty, and Arsenal might have been facing a far more uncomfortable finish.
To make matters worse for Atlético, the incident unfolded just moments before Bukayo Saka struck what proved to be the decisive goal. One contentious call, then a clinical finish at the other end. The sense of injustice in the Spanish camp doubled in an instant.
And that was only one of several flashpoints that left the visitors simmering.
The Arsenal box became a battleground in the second half, with Antoine Griezmann also left appealing for a spot-kick. During a frantic passage of play, the Frenchman appeared to be trodden on by Calafiori as he tried to wriggle free. Griezmann went down, arms raised, looking straight at the referee.
This time VAR did intervene, but not in Atlético’s favour. The review concluded that Marc Pubill had already committed a foul earlier in the move, wiping out the entire sequence. With the offence in the build-up confirmed, referee Daniel Siebert was not called to the monitor and the Griezmann incident was effectively erased from the record.
The pressure only intensified as the clock ticked down.
Giuliano Simeone then had the kind of chance that can define a career. Released through the middle, he rounded David Raya and suddenly stared at an open goal, the away end already half-celebrating the equaliser. Under pressure from Gabriel, his effort skewed agonisingly wide, bobbling past the far post instead of nestling in the net.
He immediately turned back to Siebert, arms out, insisting he had been bundled over by the Brazilian defender as he shot. Again, nothing. No whistle, no review, Arsenal surviving by the width of a post and the referee’s conviction.
While his son vented online, Diego Simeone chose a very different tone under the glare of the cameras.
The Atlético coach did not hide his belief that key calls had gone against his side, particularly the Griezmann episode, but he refused to let the narrative of the night be reduced to refereeing alone.
“I won’t focus on something simple like the Griezmann incident. It’s obvious, it was a foul. The referee said there was a foul by Marc [Pubill] on one of their players,” he admitted in his post-match duties. “I won’t focus on that. It would be an excuse, and I don’t want to make excuses. If we were eliminated, it's because our opponent deserved to advance. They were clinical in the first half and earned their place. But what I feel is tranquillity, peace; the team gave everything they had.”
That blend of irritation and acceptance summed up Atlético’s night. They raged at the details, but could not escape the broader truth: Arsenal had punished them when it mattered.
Simeone also reserved a notable slice of respect for what Mikel Arteta has built in north London. He recognised that this was not a plucky upstart edging past Atlético, but a fully formed project operating at the very top level, backed by serious investment and a clear tactical identity.
“They have a team and a manager that I like. They follow a consistent approach, with significant financial resources that allow them to compete like this. Congratulations. We'll continue with our work, without getting bogged down in a detail of something that's so obvious,” he said.
So the semi-final ends with two Simeones offering two responses: the son, raw and indignant on social media, freezing controversial moments in time; the father, battle-hardened, choosing to absorb the blows and look ahead.
The scoreboard will not change. The screenshots will not be forgotten. The real question now is how long this sense of grievance will fuel Atlético’s next European charge.
