A first-half brace from Charles De Ketelaere laid the foundation for victory before Hans Vanaken and Romelu Lukaku added further goals to send the Red Devils into a last-eight meeting with Spain.

The United States briefly threatened a comeback when Malik Tillman equalised with a deflected free-kick, but Belgium quickly regained control and never looked back.

Rudi Garcia's side made the perfect start, taking the lead after just nine minutes when Nicolas Raskin's cross found De Ketelaere, who finished from close range after the American defence failed to deal with the delivery.

The hosts responded midway through the first half. Tillman's free-kick took a deflection off the Belgian wall before looping beyond the goalkeeper to bring the United States level and ignite the Seattle crowd.

Belgium restored their advantage almost immediately, however. Leandro Trossard delivered an inviting cross into the box and De Ketelaere rose highest to head home his second goal of the evening.

The decisive moment arrived shortly after the restart. Goalkeeper Matt Freese hesitated while attempting to play out from the back, allowing De Ketelaere to dispossess him before squaring for Hans Vanaken, who calmly finished into an empty net.

The United States pushed forward in search of a route back into the contest, but Belgium remained composed defensively and continued to threaten on the break.

Romelu Lukaku wrapped up the victory in stoppage time after Chris Richards surrendered possession in his own half, allowing the veteran striker to drive home Belgium's fourth goal.

The result ends the United States' World Cup campaign on home soil, while Belgium advance to a quarter-final showdown with European champions Spain.
