Bench influence and formation drift

The manager’s decision to bring on Martinelli altered the team’s width and pace. The substitutions nudged the team into a more dynamic 4-3-3 shape at times, with Martinelli operating high and wide. Bilbao’s defense found it hard to track the runs from the left and central areas. The changes also helped maintain pressing intensity higher up the pitch, restricting Bilbao’s build‑up and forcing errors. By adjusting the shape and tempo, Arsenal created dangerous moments and ultimately converted them into goals.

Press and tempo management

Arsenal’s pressing approach remained sharp in the second half, especially after the goal. They pressed higher up the pitch and recovered possession quickly, denying Bilbao time to build. The increased tempo helped sustain pressure and keep the tie within Arsenal’s control. The coaching staff will view this as evidence that the squad can maintain intensity over long periods, even away from home in Europe. The performance also highlighted the value of a flexible plan that can adapt to how the game unfolds.

Player performances

Several players stood out as contributors to a comprehensive away win. The sequence of events and the manner in which they executed key moments reflected a balanced, effective performance from the front to the back. Martinelli’s impact upon his introduction was immediate and transformative, while Trossard’s late finish demonstrated clinical finishing in the closing stages. The defense capped a disciplined night with resolute organisation and clear communication. Across the board, players delivered both individually and collectively, reinforcing the impression of a well‑coordinated squad prepared for the campaign ahead.

Leandro Trossard and others
