The Emirates, on a Tuesday in May, takes on a colour the rest of the football season does not produce. Twenty years since Arsenal last walked into the second leg of a Champions League semi-final, the stadium’s ritual on European nights has become something the club’s marketing did not invent: it grew, the way these things grow, out of the shortage of them. The team have reached this stage exactly once since the move from Highbury, in 2009, and lost. Tuesday is the chance to correct a two-decade absence.
Arsenal go into the second leg level at 1-1 with Atlético MadridT1, UEFA, after Viktor Gyökeres’s first-half penalty was cancelled out by Julián Álvarez from the spot after the interval at the Wanda MetropolitanoT1, UEFA. Mikel Arteta’s side remain unbeaten in this season’s UEFA club competitionT1, UEFA; Diego Simeone’s Atlético have lost only one of their last twelve European away matchesT1, UEFA. The aggregate winner travels to Budapest on 30 May for the final, against PSG or Bayern Munich, whose own semi-final remains in the balanceT1, UEFA.
The temptation, from north London, is to read this as Arsenal’s tie to lose. The temptation is wrong. Atlético arrive at a stage of the competition they have learned, over Simeone’s fourteen-year tenure, to treat as familiar terrain. Cholismo is not the caricature the English press still occasionally writes about. The 2024-25 version of the model is something altered: a back four that defends in a 4-4-2 mid-block but transitions into a 3-2-5 in possession, with Pablo Barrios and Rodrigo De Paul flanking a Koke who plays now from the half-space rather than the centre. Marca’s tactical desk has been running that read for a fortnight; AS, in coverage anchored by Manu Sainz, has framed the tie not as an upset bid but as Atlético’s ninth Champions League knockout round in twelve seasons. The competition’s grammar is, for them, native.
Look at the first leg with that in mind. Gyökeres’s penalty was the product of a press Arsenal sustained for nine minutes around Atlético’s left-back; the foul was Reinildo Mandava’s, on Bukayo Saka, after Arsenal had forced six consecutive throw-ins inside the Atlético half. That was the period Arteta’s side dictated. They could not sustain it. Atlético’s response was the response Simeone’s sides have always produced when shaken: shorter blocks, wider mid-press, José María Giménez stepping out to break Martin Ødegaard’s first touch. Álvarez’s equaliser came from a foul Declan Rice committed in central traffic, on a recovery sprint that arrived a half-second late.
What Arteta will change at the Emirates is the question. Arsenal’s home performances in this competition have been, by Opta’s possession-value modelT1, Opta, the strongest of any side in the round of sixteen and quarter-finals; the underlying numbers have for two months suggested a team capable of beating any European opponent at the Emirates, when Saka and Gabriel Martinelli are both fit and the press triggers fire in the opening twenty minutes. Both are fit. The press triggers, on the evidence of the second half in Madrid, need recalibrating. The geometry that worked against Real Madrid in the quarter-final, with Rice dropping between the centre-backs and Ødegaard pushing into the half-space behind Antoine Griezmann, will not survive Atlético’s compactness without an additional runner. Mundo Deportivo has been pointing, all week, to the underused Mikel Merino as Arteta’s likely answer: a third arriving body in the box, a profile Atlético’s central pairing has historically struggled to track when the ball is delivered low rather than crossed.
Atlético’s plan is harder to mistake. Simeone has, in his pre-match work this season, built every European away tie on the same sequence: absorb fifteen minutes, take the sting from the home crowd, transition through Griezmann’s drop into the ten space. The threat that broke Internazionale in the round of sixteen and Borussia Dortmund in the quarters was the same threat. Álvarez, on form, is the cleanest finisher Atlético have signed since Diego Costa. L’Équipe’s coverage of the first leg, written from Madrid by Régis Dupont, made the point that Arsenal’s centre-backs, William Saliba and Gabriel Magalhães, dealt with Álvarez’s runs in behind better than any pairing he has faced in the knockout rounds. Tuesday will test whether they can do it for a second ninety minutes, this time with the away-goal incentive removed and Atlético free to chase the tie into extra time without the old penalty for conceding at home.
There is a reading of Arsenal’s season that locates Tuesday as the night the Arteta project is judged on. It is not the only reading, but it is the honest one. Five years in, two Premier League near-misses behind, an FA Cup the only major silverware on the wall, Arteta has built a side that El País described, in its weekend long-read, as the most internally coherent European project in England. The next sentence in that same piece noted that internal coherence is the trophy you win when you have not yet won the trophy. The Emirates is the chance to close the gap between the two.
The cup-tie within the cup-tie is the one between the two managers. Arteta studied under Pep Guardiola; Simeone built a counter-revolution against the Guardiola school. The first leg suggested Arteta has read the counter-revolution. Whether he can break it at home is the night’s narrower question. The wider one is what a final between Arsenal and either PSG or Bayern would say about the current shape of European football: a competition increasingly dominated by sides with positional-play DNA (Arsenal, PSG, Bayern under Vincent Kompany) and one outlier, Atlético, who have spent the season demonstrating that the older Italian-school grammar still has a semi-final in it when applied with the discipline Simeone has not, in fourteen years, allowed to slip. The Emirates on Tuesday is not just a tie. It is a referendum on which of those two grammars the continent’s spring belongs to.
