WATCH: Russian Fans Go Wild After World Cup Upset of Spain in PKs

It's party time in Moscow after Russia upsets Spain in World Cup to reach the quarterfinals.

Russia will appear in the World Cup quarterfinals after shocking Spain in the round of 16 on penalty kicks on Sunday–and the thousands of fans at Moscow's watch party outside of the Luzhniki Stadium predictably went nuts.

After regulation and extra time ended with a 1-1 time, Russia goalkeeper Igor Akinfeev made two saves, including the decisive kick save on Iago Aspas, to help Russia win the shootout 4–3.

The mood at the watch party was clearly tense in the build-up to the decisive kick, but as soon as Akinfeev made the clinching save, the throngs of supporters eruputed in joy in celebrating the upset victory.

Expect a party in Russia for the rest of the week until the next match on Saturday.
