Belgium initially set up in a 3-4-2-1 formation, utilizing Lukaku as the focal point of their attack. Japan, in contrast, played in a 4-2-3-1 with a compact midfield that stifled Belgium's creative players early on. Japan's pressing forced errors from Belgium, leading to a quick transition that brought their first goal early in the second half. However, with Lukaku's introduction, Belgium shifted tactics to better exploit the wings and height advantages, which proved essential in their comeback. The defenders adapted to monitor Japan's counters, but the breakthrough came from set plays and swift ball movement rather than reliance on individual brilliance. Chadli's late goal was emblematic of strategic persistence and tactical dynamism, marking a critical tactical success.
