Mikel Merino became the first substitute in World Cup history to score the winning goal in two knockout rounds, sealing a 2-1 victory over Belgium on 11 July 2026 to send Spain into the semi-finals. His second stoppage-time strike—just 15 months after Mikel Arteta first deployed him as a striker at Arsenal—has rewritten Spain’s attacking strategy.**

**How did Merino go from Arsenal trial to World Cup hero?** The turning point came in **February 2025**, when Arteta, facing an injury crisis, moved Merino from midfield to centre-forward against Leicester City. He scored twice in a 2-0 win, exposing a striker’s instincts hidden behind his midfield pedigree. Spain’s head coach, Luis de la Fuente, later mirrored that move, trusting Merino’s penalty-box instincts in knockout deadlocks.

**What makes Merino Spain’s most effective super sub?** At **30**, Merino has spent **39% of his Arsenal minutes as a striker**, a role he’s dominated with physicality and timing. Against Belgium, he latched onto Ferran Torres’ pass in stoppage time, replicating his **round-of-16 winner against Portugal**—a feat no substitute had achieved in World Cup history. His versatility—playing as a pivot, false nine, or target man—has made him Spain’s most unpredictable weapon.

**Why is Merino’s physicality the key to Spain’s attack?** Unlike striker Mikel Oyarzabal, who relies on clever runs, Merino’s **“duel-monster” reputation** from Real Sociedad translates into aerial dominance and defensive threats. His first touch and anticipation—praised by Arteta as “goal threat” material—have forced Belgium and Portugal to double-mark him. Even when crosses sail wide, his movement draws defenders out of position.

**What’s next for Merino in the World Cup?** Spain now face a semi-final clash with either France or Brazil, where Merino’s ability to unlock stagnant attacks could decide the tie. If he scores again, he’ll cement his place in history—not just as a substitute, but as the player who redefined Spain’s knockout-phase resilience. For now, his **two knockout winners in two games** have made him the tournament’s most clutch performer.
