Arsenal left the Estádio José Alvalade with exactly what they needed — a one-goal lead and renewed belief — after Kai Havertz’s stoppage-time strike settled a tightly contested UEFA Champions League quarter-final first leg in Lisbon on Tuesday night.
The German substitute bundled home a composed finish in the 91st minute from a perfectly weighted Gabriel Martinelli pass, breaking a stubborn deadlock that had tested Arsenal’s patience for the full 90 minutes before that moment.
The result carries significant weight when you consider the context surrounding Mikel Arteta’s side going into this trip. Back-to-back domestic defeats — including a painful FA Cup exit at Southampton — had reduced their season aspirations from four potential trophies to two, making this Champions League run the clearest remaining route to a defining achievement. Winning in Lisbon, therefore, was not just tactically important; it was psychologically essential.
Sporting had gone into the fixture as the form side at the Alvalade, having not lost at home in 17 consecutive matches across all competitions, and having won all five of their Champions League home games this season. That record included a famous result against holders PSG, making this a genuinely hostile environment for a visiting team already carrying the bruises of a difficult week.
The opening exchanges reflected that difficulty. Both sides struck the woodwork inside the first 15 minutes, with David Raya producing a superb tip against the bar before Noni Madueke’s corner cannoned off the frame. After that early burst of energy, the game settled into a cautious, compact affair, with Sporting’s backline largely neutering Viktor Gyokeres — returning to the club where he scored 97 goals in 102 appearances — who ended the first half with just nine touches.
Martin Zubimendi thought he had given Arsenal the breakthrough after 63 minutes, but VAR chalked off his effort after detecting Gyokeres offside in the build-up. The decision frustrated the Gunners, who were growing in control of possession but struggling to generate clear openings. As the clock ticked down, Arteta threw on Max Dowman and Martinelli, and the latter immediately injected urgency into a sluggish Arsenal attack.
Raya was called upon twice in quick succession late on, producing a double save at his near post that kept the scores level and gave his team the platform to steal a winner. That is precisely what arrived when Martinelli, sharp and direct from the moment he entered, found Havertz arriving at pace into the box, and the German coolly slotted past Rui Silva to trigger euphoric scenes from the travelling support.
Arsenal head coach Mikel Arteta had spoken before the game of being “hungrier than ever” to reach successive Champions League semi-finals for the first time in the club’s history. The victory at the Alvalade puts that ambition firmly in their own hands ahead of next Tuesday’s second leg at Emirates Stadium. Sporting’s head coach will take confidence from how effectively his side suppressed Arsenal’s attack for long stretches, and that energy could make the return leg a very different proposition.
It is also worth noting that Sporting will have centre-back Ousmane Diomande and striker Luis Javier Suarez available at the Emirates after an earlier yellow card confusion was corrected by UEFA. That decision removes one potential advantage Arsenal might have hoped to exploit. With a 1-0 aggregate lead and home advantage, Arteta’s side are in the driver’s seat — but nothing about this tie suggests the second leg will be straightforward.
From an analytical standpoint, the narrow victory continues what has become something of a theme for Arsenal this season: winning games through individual moments of quality rather than dominant spells of play. It raises questions about whether that model can sustain them through a semi-final and, potentially, a final, but right now the only thing that matters is progression. And on that score, they have given themselves a very workable position.
