Jan Vertonghen's late goal gave 10-man Belgium a 1-0 victory over South Korea and a 100 percent record in World Cup Group H.
The Belgians kept the upper hand throughout the game despite losing Porto midfielder Steven Defour, who made no protest over his sending-off just before half-time for a two-footed challenge.
Substitute Divock Origi, who scored the winner against Russia, again made a forceful impact.
He powered in the shot from the edge of the penalty area in the 77th minute that Korean goalkeeper Kim Seung-Gyu could not hold, giving Tottenham centre-back Vertonghen a simple shot in.
Belgium finished top of Group H with nine points and now play United States in the round of 16 in Salvador on Tuesday. They go through with Algeria who held on to second place with a 1-1 draw against Russia.
