Who can be the first to secure a spot in the next round? Spain has a slight overall advantage, but Belgium still has a chance for an upset.

The most fascinating aspect of a knockout match is that any detail can change the outcome. Spain and Belgium are evenly matched, so the game is unlikely to be one-sided.
Spain has more mature team coordination, and midfield control remains their biggest advantage. If they can maintain passing accuracy and reduce errors, they are expected to keep Belgium under pressure.
Belgium's biggest weapon is counter-attacking efficiency. Once Spain pushes too deep, Belgium's forwards can use their speed to launch quick advances, so Spain must be wary of the space left during transitions.
Both sides are expected to play cautiously, and the first half may not see many goals. Real changes are more likely to occur in the second half, as the pace picks up and opportunities gradually increase.
Considering overall strength, squad depth, and ball possession, I slightly favor Spain.
Prediction: Spain 2:0 Belgium.
Expected total goals: 2. Spain is likely to advance with solid defense and higher offensive efficiency.
The above is only a pre-match personal opinion and score prediction. Football matches have considerable uncertainty, and the final result still depends on the actual game.#预测世界杯西班牙VS比利时
