Arsenal’s 2-0 Win at San Mamés Arsenal kicked off their Champions League campaign. A powerful 2-0 away victory over Athletic Bilbao at the storied Estadio de San Mamés. First Gabriel Martinelli, then Leandro Trossard whose contributions proved decisive. It was Gabriel Martinelli who broke the deadlock. The Brazilian forward, aged 24, came off the bench in the 71st minute to replace Eberechi Eze. Just 36 seconds after stepping on the pitch, with only his fourth touch. He fired the ball under Athletic Bilbao keeper Unai Simón to make it 1-0.
The second goal was Trossard’s turn to find the net. Late in the match (87′), Leandro Trossard scored (his age and nationality as above), with the assist coming from Martinelli. This time, Trossard’s effort took a deflection off a Bilbao defender (Dani Vivian) before beating the keeper. That goal sealed the win and underscored the tactical impact of Arsenal’s substitutions. Beyond the goals themselves, this match showed sharp contrasts.

With Athletic Bilbao defending stoutly. Arsenal’s attacking intent was evident. But without a clinical touch until Martinelli’s lightning moment. The substitutions forced momentum and paid off in spectacular fashion. Also interesting. He had earlier suffered a head injury from a clash but continued until around the two changes. His presence had threatened, though he was unable to convert any chances. The result is more than just three points and a clean sheet. It’s a statement about Arsenal’s depth, their ability to change a match from the bench, and the sharpness of key individuals when it counts. Martinelli’s quickfire opener and Trossard’s composed finish represent the kind of moments that win tight games.
This performance gave confidence to the squad that they can grind out results even when the early going is tough. Would you like a breakdown of player ratings from this match, or what this means for their upcoming fixture?
