Spain vs Belgium: World Cup quarter-final storylines, form and what to watch

Spain have made their tournament about discipline. Unbeaten across their last seven outings, they have leaked just two goals in that run and kept five clean sheets, a defensive rhythm anchored by David Raya and a back line where teenager Pau Cubarsí keeps growing into the big stage. A 4-0 dismantling of Saudi Arabia and a hard-earned 1-0 win over Uruguay show a side that can dominate or grind, and with Rodri conducting from deep, they will want the ball and the tempo.

Belgium bring a different energy. Marc Wilmots' successors have leaned into attack, banging in goals at a rate of more than two and a half per game over the past six months, including a 5-1 rout of New Zealand and a gutsy comeback against the USA. Kevin De Bruyne remains the creative heartbeat, Jérémy Doku the game-breaker out wide, and Romelu Lukaku the reference point up top, giving the Red Devils a threat Spain have rarely faced at this tournament.

The tactical battle almost writes itself. Spain will try to starve Belgium of space and turn possession into slow suffocation; Belgium will look to spring quickly through Doku and De Bruyne the moment the Spanish press is broken. Whoever wins the midfield exchanges around Rodri, Fabián Ruiz, Youri Tielemans and Amadou Onana is likely to shape the night.

There are selection questions to relish, too. Nico Williams and Mikel Oyarzabal give Luis de la Fuente's Spain pace and end product from wide areas, while Belgium can turn to Leandro Trossard and Charles De Ketelaere off the bench to change the picture late. In a single-leg knockout, the manager who reads the momentum first could tip a finely balanced tie.

For supporters, this is the kind of quarter-final the World Cup is built on: an unbeaten Spain that concedes almost nothing against a Belgium team that scores almost at will. Both nations feel the pressure of expectation and the pull of a semi-final within reach, and neither will want to blink first.
