Charles De Ketelaere starred with a brace, Hans Vanaken capitalized on a costly goalkeeping error, and Romelu Lukaku added a late fourth as the Red Devils swept aside the tournament co-hosts at Seattle's Lumen Field. The match had been dominated by controversy before kick-off after FIFA overturned the suspension of US striker Folarin Balogun, allowing him to start following intense lobbying. However, Balogun failed to make an impact as Belgium took control from the outset. De Ketelaere opened the scoring in the ninth minute before Malik Tillman briefly restored hope for the hosts with a deflected free-kick in the 31st minute. Belgium responded immediately, with De Ketelaere heading home two minutes later to regain the lead. Vanaken extended the advantage in the 57th minute after goalkeeper Matt Freese's disastrous attempt to clear the ball outside his area, while Lukaku sealed the emphatic victory in stoppage time. Belgium captain Youri Tielemans admitted the pre-match controversy motivated his teammates. "We told ourselves we needed to do our talking on the pitch. That's what we did today. I'm very proud of the team," he said. US coach Mauricio Pochettino acknowledged his side failed to perform. "Today we were not the same team that we have been during the tournament. It was a very bad day." Belgium will now face Spain in Friday's quarter-final in Los Angeles.
