It was, perhaps, Russia's most famous triumph since 1945. All across the capital, citizens began to party as such. From cars, and from bars, Russians chanted the name of their country in unison. "Ros-si-ya, Ros-si-ya."
In the central Chistye Prudi district, traffic ground to a halt as two men, deep in alcoholic haze, staggered back and forth across the main boulevard, flags draped across their shoulders.
On another day, they would have risked death. But not today. Instead, Moscow's usually irritable drivers gave hi fives and honked back in joyful rhythm. Foghorns and the enduring notes of Ro-Si-Ya provided a harmony of sorts. For several hours now, Moscow has been shaking to this unusually disruptive tune.
At the "Spanish Canteen" tapas bar around the corner, it was a bittersweet scene. The chef had been supporting Spain, and went into hiding sometime after his team missed the crucial fourth penalty. For a few moments, the paella orders stopped. Waiting staff said he had been seen crying.
As the wine flowed, and, presumably, the chef cried a bit more, the salsa music was switched on, and the dancing began.
"Spanish, go home!" two of them chanted, before turning to their queso and Rioja.
Yekaterina Alexandrova, 54, a former Russian embassy official in Spain, Cuba, Costa Rica and Ecuador, said she had arrived at the bar with split loyalties. She and her son were avid Barcelona fans, but country came first today. They were rooting for Russia. Her "enigmatic soul" could hardly explain how it had happened.
Eventually, the chef Fernando Ruiz del Castillo returned to the bar. Sportingly, he suggested the better team won.
Not even the Russian supporters could agree. With a possession ratio of 80-20, and a debatable penalty to draw level, the Russian side clearly rode their luck today. One of the patrons, Igor Bushmakin, 31, who was seen wearing a kokoshnik tiara, said the Russia team was "a level lower than the Spaniards," and were forced to play disruptive football. It said a lot that the goalkeeper was the man of the match in altogether dour game, he added.
Not that any of that mattered. Russia had set up the defence brilliantly, parking a "convoy of tanks" across the middle of the park. The Spanish simply couldn't see a way through.
"We do defence well in our country, and now the Spanish know it," said Mr Bushmakin.
"Putin promised us all a technological breakthrough, and this, I'm sure as hell, is it!"
The underdog when it comes to world football, and of course hosting the games. I had a sneaky suspicion this would happen.
All the football fans, love being in Russia, and this will probably go down as the best world cup ever, for feeling the love of the game, and a safe place to be, no violence and the enjoyment of being in a multicultural atmosphere.
That being said, I am not even a football fan, but see a world brought together by a true sporting atmosphere, lifts my spirit.
