Sounds of cheering were heard in the streets at the kickoff. More noise followed when Messi scored early in the game, and the din of air horns penetrated the morning air.
But an eerie silence then set in, as what was supposed to be an easy match turned challenging. Saudi Arabia rallied with two second-half goals, and one of World Cup's favorites instead suffered one of its biggest upsets.
“The truth is, this is a disappointment, a big disappointment,” said Alejandro Pintos, a 36-year-old locksmith who opened his shop later than usual to watch the game. “This was the match that we had no choice but to win.”
Pintos said the national team was “very disorganized” — something he found particularly frustrating, given its 36-match unbeaten streak leading up to the tournament.
Local media quoted Messi as saying he was just as shocked as the fans on how things had turned out.
“It’s a very strong blow,” Messi said. “We didn’t expect to begin this way.”
Other fans took to social media to complain about three potential Argentina goals ruled out on offside calls.
Argentines were counting on the World Cup to bring a glimmer of a hope to a country that has been economically stagnant for years, suffering a nearly 100% inflation rate and where close to four in 10 live in poverty.
“I’m really quite bitter,” said Josefina Licera, a 27-year-old social worker, as she waited to take a bus to work. “I was really sure we were going to win, and it was a big surprise.”
Susana Leguizamón, 55, woke up early, put on her blue-and-white-striped Argentina jersey and was ready to celebrate.
“I was very, very, very surprised,” she said. “The truth is, we underestimated our rival.”
But Santiago Babarro, 40, said he wasn’t too shocked by the loss.
“The same thing always happens to Argentina," the retail worker said. "We say, ‘This is an easy match, we can win it easily,’ and then, bam! They put us in our place. We always believe we’re more than what we are.”
Sebastián Fabre said he woke up with an uneasy feeling and was worried about what he said was overconfidence by Argentina's fans.
“There was way too much unfounded optimism. I didn’t want to say anything but I think we were all way too overconfident,” he said.
Leguizamón, who walked to her job at a restaurant still wearing her Argentina jersey, said she could feel the suffering of those around her.
“Everyone is very sad, very sad,” she said. “We all woke up with lots of hope.”
Some fans saw a silver lining in suffering adversity at the outset of the tournament. Argentina next plays Mexico on Saturday in the second Group C match.
“Really, it’s better that this happened in the first match and not in the quarterfinals,” Fabre said. “That’s the positive side to this.”
“A trip is not a fall, as we say here,” she said, using a common Argentine expression. “I’m a big fan of the national team and I get in a really bad mood when it loses but my hope is intact.”
The saddest part, said 21-year-old retail worker Florencia Folgoso, "is having to go to work after watching a match that we lost. You already start the day with the left foot.”
