Before this match even started, it's fair to say that most A Coruña residents expected a loss for their team. Deportivo are in the relegation zone and Barcelona are atop the league table.
When the visitors opened the scoring barely three minutes in, it was a bad sign of things to come.
But the fans that packed Riazor did not get discouraged. Nor did they give up after the second goals was scored just five minutes later.
What happened at the 18-minute mark, though, was the stuff that makes fans of any team proud.
When Lionel Messi scores to put Barça up 3-0, most teams rightly feel deflated. Many fans would leave and give up. Some would even start booing their team off the pitch, even if the result was expected.
Not in A Coruña. Even as Messi was still embraced by his teammates, the stadium drowned out any sounds of celebration as they started a chorus of cheers in support of their team.
The fans knew they were in for a rout, but were not going about to turn on their team. Instead, they got louder and louder, trying to inspire even one goal to earn back some dignity.
Perhaps the backing of the fans inspired the players because before we knew it, Deportivo were within a goal of drawing level.
The fans stayed boisterous throughout the match even as Barça twice built a two-goal lead. The stadium erupted when Jordi Alba scored an own goal that allowed the hosts to again get within a goal.
The highlight of the night came when the final whistle blew and Riazor eruped with a series of chants and cheers praising their club.
Banners, scarves, and flags were waved and everyone in the building rose to their feet to praise their team for scoring four goals on one of football's greatest teams.
Barcelona has fans all over the world due to their successful history, especially over the last few decades.
On Saturday night, Deportivo fans showed that while their numbers are dwarfed by that of Barcelona, their loyalty, dedication and connection with their team is something that most global fans cannot and will not ever experience.
It is these moments that make Spanish football such a joy to watch.
