Arsenal vs Atlético Madrid Preview: The English-Knockout Curse, Ødegaard's Knee, and a First Final Since 2006
Atlético Madrid don't lose European semi-finals to English clubs. They've played three, won three, against Liverpool in 2010, Chelsea in 2014, and Arsenal in 2018. Eleven of their last fifteen two-legged European ties against English opposition have ended in their favour.
The number that breaks the spell is the next one. Atléti have won just two of their last twelve actual matches against English teams in UEFA competition, the aggregate record sounding untouchable while the road form says they get there in spite of what happens on the pitch in England. Tuesday at the Emirates is the cleanest test of either reading the tie has had, with the aggregate level at 1-1, away goals long since gone, and a place in the final waiting for the side that finishes the job.
The road form that betrays the record
The first leg told both stories in ninety minutes. Atléti played the kind of football that gets sides through Champions League knockout ties, dominating the second half once Simeone went to a back five at the break, drawing the penalty Julián Álvarez converted, putting the Emirates' best-defended Arsenal team of the season into thirty-five minutes of real pressure. They also failed to win the leg they needed to win.
The 2-0 over Valencia at the Mestalla on Saturday is the form everyone will quote. Simeone made eleven changes, debutants Iker Luque and Miguel Cubo scored either side of the eighty-minute mark, and Valencia did not register a shot on target. It was the eighty-second minute of a La Liga rotation match. It is not the side Arsenal will face on Tuesday.
0
Álvarez's UCL goals this season, the most ever by an Atléti player in a single Champions League campaign.
The road problem is the one that has not gone away. Atléti have conceded at least twice in seven of their last ten games on the road across all competitions, including in the Copa del Rey final defeat to Real Sociedad on the 18th of April. Their league form before the Athletic Club win in late April had been four straight defeats. The version of Atléti that arrives in London on Tuesday is the one that wins on heritage and aggregate, not the one that controls ninety minutes away from the Metropolitano.
The trio that has only conceded eleven in twenty-two
Arsenal arrive at this leg as the only unbeaten team left in the competition: ten wins and two draws across the campaign, five goals conceded in twelve matches before the first leg, and a Premier League run-in where the 3-0 against Fulham on Saturday kept Manchester City six points behind with three matches left.
The defensive numbers go beyond the cumulative tally. In the twenty-two Champions League matches that David Raya, William Saliba, and Gabriel Magalhães have started together, Arsenal have conceded eleven goals at half a goal per ninety minutes and kept thirteen clean sheets. The trio is the closest thing the modern Champions League has to a guaranteed defensive floor.
The first leg is the one wrinkle in that pattern. Arsenal carried big stretches of the match, conceded the equalising penalty after a Ben White handball from a Marcos Llorente shot inside the box, and had a second penalty for them, awarded by Danny Makkelie for a Hancko foul on Eberechi Eze, overturned by VAR. Arteta called the overturn “not a clear and obvious error.”
This changes the course of the tie, and it cannot happen.

The aggregate scoreline says they should be 2-1 ahead of this match. They are not.
Ødegaard's knee changes the shape of the press
The Arsenal team news pivots on a single knee. Martin Ødegaard suffered a knee injury in the first leg, missed the Fulham game on Saturday, and is rated a doubt for Tuesday. Arteta said after the Fulham win that both Ødegaard and Kai Havertz would do everything to be ready, but with Ødegaard's third knee injury of the season already on his record, the more likely call is the cautious one.
If Ødegaard does not start, Eberechi Eze plays as the number ten. The shape stays a 4-2-3-1 with Saka on the right, Trossard on the left, Eze tucked in between Rice and Zubimendi, and Gyökeres leading the line after his brace against Fulham. Saka's role is the one to watch. He played thirty-odd minutes off the bench in Madrid, then started against Fulham and was withdrawn at half-time after scoring and assisting in his forty-five, and arrives at Tuesday with the workload of a player Arteta is openly ramping up while protecting.
For Atléti, Diego Simeone effectively confirmed his XI by resting it. The eleven changes against Valencia were a deliberate move to send the Madrid first leg's starting team into the Emirates fresh, and the side that walks out on Tuesday is expected to mirror that one: Oblak; Llorente, Pubill, Hancko, Ruggeri; Giuliano Simeone, Cardoso, Koke, Lookman; Álvarez, Griezmann. Pablo Barrios's hamstring keeps him out, and Hancko's ankle, which was a doubt across the weekend, has been declared fit.
London, Arsenal's ground. We will go and play with everything.
— Diego Simeone
Predicted Arsenal XI (4-2-3-1): Raya; White, Saliba, Gabriel, Hincapié; Rice, Zubimendi; Saka, Eze, Trossard; Gyökeres
Predicted Atlético Madrid XI (4-4-2): Oblak; Llorente, Pubill, Hancko, Ruggeri; G. Simeone, Cardoso, Koke, Lookman; Álvarez, Griezmann
A 21-year home knockout streak that ended in April
Atléti's 21-game unbeaten run in home Champions League knockout ties, stretching back to a 2-3 quarter-final defeat by Ajax in the 1996/97 season, ended at the Metropolitano in April against Barcelona. Twenty-nine years of home knockout immunity, gone in one April evening, two weeks before this semi-final began.
They survived that round only because their 2-0 first leg at the Camp Nou had given them enough cushion. The version of Atléti that walks out at the Emirates does so without the aura of a home leg controlled, and without the buffer of one in hand.
The only knockout tie these two clubs have settled before this one was the 2018 Europa League semi-final, won by Atléti on aggregate. The first leg of this one is now the fourth meeting and a 1-1 draw that solves nothing.
The high line that keeps getting caught
Atléti's defensive shape under Simeone is the foundation of the second leg, but the wrinkle is the version Arsenal will face. The first-leg shift to a back five at half-time, with Hancko dropping into a third centre-back role, was the moment Arsenal lost grip of the game. Whether Simeone starts that way at the Emirates or saves it for the second hour is the tactical question that drives the rest.
Across the 2025/26 Champions League, only Qarabağ and Real Madrid have faced more shots than Atléti, and big gaps left behind a high line have been a recurring theme. Six months on from the 4-0 at the Emirates in October, with Atléti needing to win or push the game past ninety to advance, Simeone has to ask his back four to step up the pitch in a way the Madrid leg never required.
Arsenal's answer is the same one it was in October. Build through Zubimendi and Rice, who screen the back four and let the centre-backs hold a deeper line than most possession-based sides do, and play forward into Gyökeres or out to the wide channels for runners. Saka behind that back line under pressure is the sharpest version of it, and Trossard's two-footed counter-attacking width on the left adds a second route that does not need long phases of possession to threaten.
Two duels that change the tie
Bukayo Saka vs Dávid Hancko. The right side of Atléti's defence is the most exposed seam in this tie. Hancko committed the foul that won Gyökeres the first-leg penalty, missed the Valencia rotation with an ankle problem he has carried since the Athletic Club game in late April, and is expected to start at left centre-back on Tuesday with that ankle declared fit. Saka, on the other side, has built up only seventy-five minutes of football across two appearances in eight days and is fresher than at any point since his Achilles injury. Arsenal score 2.6 goals per game in the Champions League when Saka starts, and the duel that barely got going in the first leg, with Saka coming off the bench in Madrid, is the one that runs from minute one at the Emirates.
Julián Álvarez vs William Saliba. Álvarez leads the entire 2025/26 Champions League in high-intensity pressures per ninety. The first-leg penalty he converted was his twenty-fifth Champions League goal in just forty-one games, the fewest ever for any South American to reach that mark, surpassing Lionel Messi by a single match. The reason this matters at the Emirates is who he is going to chase. Saliba is the engine of Arsenal's build-up and the player whose ball-playing decides whether Atléti's press translates into pressure on the Arsenal goal. Álvarez's job is to harass that decision-making for ninety minutes while still being the side's attacking outlet on the break, and there has been no centre-back of Saliba's pedigree on his press list at this stage of a Champions League before.

Álvarez's high-intensity pressures per 90, the most of any player in this season's Champions League.

Arsenal six points clear of Manchester City with three matches left. Atlético fourth in La Liga, top-four already secured.
The Premier League makes Tuesday a different kind of stakes test for Arsenal. They sit six points clear of Manchester City with three matches left, on a goal difference of plus forty-one against City's plus thirty-seven, with West Ham, Burnley, and Crystal Palace as the remaining fixtures. The league is shaping into a coronation if Arsenal take care of business, even with City holding two games in hand.
A first European final since 2006 and a first Champions League title in their history sit ninety minutes plus possible extra time away.
Atléti are fourth in La Liga with sixty-three points and have already done enough to secure their top-four finish, which gave Simeone the cover to rotate eleven against Valencia. The Champions League is the only trophy with anything left in it.
The official, when announced
The referee for the second leg has not been confirmed at the time of writing. The first leg was officiated by Danny Makkelie of the Netherlands, and whoever is appointed for Tuesday inherits a tie that has been a daily officiating story since the final whistle in Madrid. UEFA's elite category provides the pool, and any appointment from it will arrive knowing the overturned penalty is the open file on the desk. Sixty thousand at the Emirates will respond to the first close call accordingly.
One night, two histories, one trip
The strange thing about a tie level at 1-1 is that everything either side has done across the season collapses into a single ninety, possibly thirty minutes more, possibly a shootout. Arsenal have not been a Champions League finalist since 2006, and the unbeaten run of fourteen matches they would have if they came through Tuesday is one their European history simply does not contain.
For Atléti, the same night carries a different weight. Antoine Griezmann, who has been directly involved in 24.2% of every Atléti Champions League goal in their history, is leaving for Orlando City in the summer. If the tie ends here, the European story of the most prolific Atléti generation in continental history ends in the stadium where they were beaten 4-0 six months ago. That is a steep ask of a side whose road form across this season has not been the form of a side that finishes work in England.
