Spain has demonstrated overwhelming dominance in this tournament, winning all three group stage matches with 8 goals scored and only 1 conceded, showcasing balanced performances on both ends. In the knockout stage, they maintained their possession-based style of play, with smooth passing combinations in midfield and attack, particularly threatening through flank breakthroughs and half-space penetrations. In terms of recent form, Spain has remained unbeaten in five consecutive official matches, with morale and fitness levels at a peak. Belgium, on the other hand, experienced ups and downs, going 2-1 in the group stage and narrowly defeating their opponent in the final round to secure qualification, exposing issues with defensive concentration. Before the quarterfinals, Belgium's performances in warm-up matches were mediocre, with concerns over key players' fitness reserves and form adjustments. Historical head-to-head records show Spain holds an advantage with 3 wins, 1 draw, and 1 loss in their last five meetings. Their most recent encounter was in the 2022 UEFA Nations League, where Spain won 2-1 at home. Belgium's sole victory dates back to a 2016 friendly, in which Spain fielded a weakened squad. In major tournaments, Spain remains unbeaten against Belgium, holding a psychological edge. In terms of key players, Spain's core midfielder Rodri has fully recovered, with his distribution and interceptions forming the tactical foundation of the team. Winger Yamal has been in hot form recently, providing assists in two consecutive matches. The injury situation is relatively optimistic, with only backup defender Gaya sidelined due to injury. Belgium, however, faces severe challenges: captain De Bruyne has returned but has yet to regain peak form; striker Lukaku experienced minor muscle discomfort in the first knockout match, and while he is likely to play, his explosive power may be limited. Additionally, the age disadvantage of defensive mainstay Vertonghen could be exposed against Spain's quick passing combinations. Tactically, Spain continues their possession-based system, emphasizing midfield triangle combinations to stretch the opponent's defense, with full-backs frequently overlapping to create local numerical advantages. Belgium relies more on counter-attacking efficiency, with the sprint speed of their front three being their greatest weapon, but their lack of midfield control makes them prone to losing possession under pressure. The key matchup in this game lies in Spain's half-space attacks versus Belgium's three-center-back system's flank protection. If Belgium fails to disrupt Spain's combination play between the center and flanks, their defense will come under immense pressure. AI comprehensive predictions give Spain a win probability of 54.4%, a draw at 35.0%, and Belgium at 10.6%.
