Argentina forward Lionel Messi has been man of the match in all four of his nation's outings at the finals, netting four goals and setting up Angel Di Maria to score the winner against Switzerland in the last 16.
Saturday's match will be Messi's 91st international, equalling Argentina great Diego Maradona in joint sixth on the nation's all-time list.
Argentina have survived six of the seven times they have had to play extra time or a shootout at the World Cup - their only defeat was on penalties to Germany in the 2006 quarter-finals.
Belgium's victory against the United States in the last 16 meant they equalled their record of seven straight wins in all competitions from 1979-80.
Belgium are through to the last eight for the second time after Mexico 1986.
Argentina and Belgium have played each other four times, with the South Americans winning three and the Europeans one, a shock success at the 1982 World Cup in Spain.
They last met when Argentina beat Belgium 2-0 in the 1986 semi-finals, Maradona scoring both goals. (Reporting by Iain Rogers, editing by Ken Ferris)
