Check out the highlights from Tuesday's last-16 World Cup clashes from Brazil.
Argentina 1-0 Switzerland (after extra time)
Angel Di Maria's extra-time winner carried Argentina into the World Cup quarter-finals after an unconvincing display against Switzerland.
About 40,000 Argentina fans were thought to be inside the Arena de Sao Paulo and Di Maria's late goal sparked wild celebrations between players and fans.
Belgium 2-1 USA (after extra time)
Belgium's golden generation earned the chance to live up to their billing as they reached a first World Cup quarter-final for 28 years with an extra-time win over the USA in Salvador.
Goals from Kevin de Bruyne and Romelu Lukaku knocked a brave and incredibly hard-working United States team out of the tournament.
Belgium will now play Argentina in a mouth-watering quarter-final in Brasilia on Saturday.
