Bukayo Saka’s composed finish just before halftime was enough for Arsenal to edge Atletico Madrid 1-0 in the first leg of their UEFA Champions League semi-final at the Emirates Stadium on Tuesday. Mikel Arteta’s side controlled large portions of the match, generating an xG of 1.58 compared to Atletico’s 0.53, suggesting the scoreline could have been more comfortable. Diego Simeone’s side showed characteristic defensive resilience but rarely threatened, leaving North London with a significant deficit to overturn in the second leg.

Key Moments

- 58′, Arteta makes his own adjustments, withdrawing goalscorer Saka and Calafiori within a minute of Atletico’s changes, shifting the team’s shape to protect the lead.
- 66′, Atletico introduce Griezmann and Julián Alvarez in a second double change, committing their most creative options in an attempt to find an away goal.
- 90′, A heated finale sees yellow cards brandished to Koke, D. Simeone, Arteta (on the touchline), and Arsenal goalkeeper Arrizabalaga, reflecting tensions as the final whistle approached.
Tactical Breakdown
Arsenal dictated the terms for most of this contest. Playing in a 4-2-3-1, Arteta’s side controlled 54 percent of possession, completed 377 of 444 passes at an 85 percent accuracy rate, and generated 13 total shots compared to Atletico’s nine. Their xG of 1.58 against an opposing 0.53 underlines how comfortably they managed the game, even if they could only convert once. Saka’s strike in the 44th minute was the product of consistent pressure in and around the box, with Arsenal recording six shots from inside the area.
The pivotal shift came just after the hour mark. Diego Simeone threw on three substitutes at once in the 57th minute, altering personnel in defense, midfield, and attack. But Arsenal matched the move almost immediately, with Arteta withdrawing Saka and Calafiori at 58 minutes and later introducing Eze and Lewis-Skelly to stabilize midfield. The double wave of substitutions disrupted Atletico’s rhythm more than Arsenal’s, and Simeone’s side never truly found the passing lanes or positional advantages they needed to threaten David Raya.
Atletico’s primary issue was an inability to create from range. Only two of their nine shots came from outside the box, and Jan Oblak was called upon just once in any meaningful sense. Their defensive shape, usually a strength under Diego Simeone, was undermined by Arsenal’s movement and Saka’s directness before his substitution. The 0.53 xG figure tells the story plainly: Atletico could not construct genuine chances at the Emirates, and they head into the second leg needing to score at least once while simultaneously stopping a side that outplayed them for long stretches.
Player Ratings
Verdict
Arsenal hold a 1-0 advantage heading into the second leg at the Metropolitano, a scoreline that gives Arteta’s squad a real platform to reach their first UEFA Champions League final. Atletico have the experience to make this a different contest on home soil, but their xG output of 0.53 and inability to register a meaningful away goal means the burden of performance falls entirely on Simeone’s side in the return fixture. For Arsenal, this was a composed, professional display that underscores just how far this squad has come on the European stage.
