Spain will arrive with the momentum of a side that has not tasted a single loss in the group, boasting a perfect 8‑goal differential and a clean sheet behindëve. Their shape is a disciplined 4‑3‑3 that presses high, forces turnovers in midfield, and lays the groundwork for transition threats that end in Oyarzabal’sTransparent 4‑goal tally and Cucurella’s two assists; set‑piece rhythm also keeps the Portuguese defenders on edge. Portugal, meanwhile, must weather that pressure with the explosive presence of Ronaldo’s late‑game poise and Fernandes’ creative pivot – still the only assist provider for the hosts – and a counter‑attack that thrives on rapid forward passes. They’ll need to tighten their shape, contain Spain’s high pressing, and use their set‑piece delivery to catch the Spaniards off‑guard in a stadium that turns the high‑stakes nerves of a round‑of‑16 clash into a living, breathing test.
