Spain deployed a 3-3-3-1 formation, utilizing a three-man defense comprised of Ramos, Piqué, and Alba, with Azpilicueta providing width as a wing-back. The midfield trio of Busquets, Koke, and Thiago worked primarily to dominate possession and conduct ball distribution. Portugal’s 4-3-3 formation, anchored by Carvalho and pushed forward by Ronaldo, was designed for quick counter-attacks. Spain struggled defensively against Portugal's pace, leading to matches of transition where Ronaldo's movement proved crucial. Each goal reflected tactical vulnerabilities, particularly set-piece weaknesses exploited by both sides. Ronaldo's exceptional ability to find space was a critical factor, culminating in his last-minute free-kick that highlighted Portugal's resilience.
