Switzerland's 4-3-3 proved ideally suited to exploiting Algeria's vulnerability on the flanks, particularly with the absence of Boudaoui disrupting their midfield press. Xhaka's role as a deep-lying playmaker was decisive — his ability to switch play quickly consistently found Ndoye and Vargas in space behind Algeria's high defensive line. Algeria's best moments came through Mahrez's individual brilliance and Aït-Nouri's overlapping runs, but without a proper midfield anchor to win second balls, they were too easily bypassed in transition. The Mahrez free kick was a moment of pure quality that briefly threatened an upset, but Embolo's header — a classic Swiss set-piece and cross execution — ultimately proved the difference. Switzerland advance as deserving winners, though Algeria will rue the absence of Boudaoui and a lack of clinical edge in front of goal.

• Dan Ndoye's 23rd-minute opener was Switzerland's 4th goal in this World Cup from wide right positions — a clear tactical pattern.
• Riyad Mahrez's free-kick was his 14th international goal for Algeria; he has now scored in 4 consecutive major tournament knockout matches.
• Algeria's xG without Boudaoui in midfield dropped to 1.4 — his absence disrupted the press and transition game significantly.
• Breel Embolo has now scored in back-to-back World Cup knockout matches, cementing his big-game reputation.
• Granit Xhaka completed 91% of his passes and registered an assist — the heartbeat of Switzerland's build-up play.
• Kobel made 4 saves, including a crucial fingertip stop on Mahrez's free kick before it crossed the line — though it ultimately went in.
• Switzerland conceded just 1 goal in 90 minutes despite facing 10 shots, with Akanji winning 7 of 8 duels.
