Spain's greatest weapon is their steel defense.

Heading into the quarterfinals, Luis de la Fuente's team has yet to concede a goal at the 2026 World Cup. They are also the most complete team in the tournament, with five unbeaten matches and no goals conceded.

With six consecutive clean sheets and over 600 minutes without conceding, Luis de la Fuente's squad boasts an unprecedented defensive system. This marks a pivotal shift in the philosophy of the Spanish team. This solidity is a "fearsome omen" for any opponent. The reigning European champions are showing remarkable maturity in composure.

Their attack may not be flashy, but Spain still demonstrates that they are one of the most exciting teams in the World Cup and a top contender for the title. La Roja under De La Fuente has become an impregnable fortress.

Compared to the opponents they have faced, La Roja always dominates possession and creates scoring opportunities at any moment. But what currently makes the Bulls feared by rivals is not their powerful attack but their unbreakable defense.

After the group stage, against opponents like Austria and Portugal with quality attacking players, those teams spent most of the match in a state of frustration, struggling to find a way past Unai Simon's goal.

In those matches, the Bilbao goalkeeper was not overly busy with spectacular saves. This shows that the defensive system in front of him is operating very effectively.

The center-back duo of Aymeric Laporte and Pau Cubarsi creates a perfect blend of experience and youth. On the flanks, Pedro Porro and Marc Cucurella provide solid corridors.

La Roja defends from a distance, starting immediately when they lose the ball. The attacking players press to stop the first counterattack. In midfield, Rodri, who orchestrates and shields space, helps Spain maintain proper team shape and avoid chaos.

The Manchester City midfielder not only helps Spain control the game's tempo but also acts as the first layer of defense in front of the backline, sparing the center-backs from facing one-on-one situations or disadvantageous transitions.

Spain's quarterfinal challenge will be Belgium. Once considered past their prime after their defeat at the 2022 World Cup, the current Red Devils boast an 18-match unbeaten streak. Belgium's improving attack is expected to give Spain's defense its toughest test since the start of the tournament.

Rudi Garcia's team scored seven goals in two knockout matches against Senegal and the USA. The Red Devils do not play overwhelming offense. They wait for opponent mistakes to execute highly effective and sharp transitions. This approach could cause significant problems for a possession-based team like Spain.

Belgium's "drills" like Charles De Ketelaere, Leandro Trossard, and Jeremy Doku promise to pose a major challenge to Spain's defense. Meanwhile, Romelu Lukaku has proven to be a strategic weapon, scoring in his last three matches when coming off the bench.

In this World Cup, Belgium is replicating the image of the 1986 generation, who eliminated Spain in the quarterfinals to reach the semifinals. The emotional comeback against Senegal and the demolition of host nation USA in the Round of 16 are proof of the Red Devils' strength.

The match between Spain and Belgium will take place at 2:00 AM on July 11. This quarterfinal clash at the Los Angeles stadium (USA) will be a showdown between the tournament's most in-form attack and the World Cup's most stable defense. Will the Bulls' record-setting defense hold firm, or will the Red Devils' momentum create the biggest shock of this year's tournament?
