Its motto is "More than a club" and Spain's Barcelona produced more than a result Wednesday routing France's Paris Saint-Germain 6-1 to qualify for the Champions League quarterfinals.
Having lost the first-leg 4-0 in Paris, few had given Barca a chance of reaching the last eight given no side had previously overturned such a deficit in the history of the competition.
But Luis Enrique's side made a barnstorming start to the match and early in the second half a Lionel Messi penalty gave them a 3-0 lead in the Camp Nou.
The home side were coasting, but just past the hour Uruguayan striker Edison Cavani's volley seemingly put PSG back in control, with Barca needing to score three more times, given the French side now had a crucial away goal.
However, with two minutes of normal time remaining Neymar's exquisite free-kick gave Barca renewed hope and two goals in stoppage time completed the most incredible of comebacks.

Those five minutes of stoppage time almost defy description.
In the 91st minute Luis Suarez, who had given Barcelona an early lead, won a penalty, which Neymar converted.
With time running out Barcelona threw everyone forward -- even their goalkeeper Marc-André ter Stegen.
And almost with the last kick of the game Barca's sixth goal came from the most unlikely of sources -- not their famed strikers -- Messi, Neymar or Suarez -- but defender Sergio Roberto, who was born in Catalonia and is a product of Barca's youth academy.
Bayern Munich's French international Franck Ribery, who played for the German club in Tuesday's 5-1 thrashing of Arsenal, described the game as "unbelievable."
In the 2005 Champions League final, Liverpool came back from a 3-0 deficit to beat AC Milan on penalties, but Barca's victory is arguably the greatest comeback in the history of the Champions League, given those frantic and frenetic final seven minute
Barca's president Josep Maria Bartomeu said on the club's Twitter feed it was an "historic achievement that will be remembered forever."
Ahead of Wednesday's game, Enrique had remained quietly confident that his team could achieve the unthinkable.
"We arrive in good form and we have to be confident," Enrique told reporters, referring to Barca's two previous league victories, where his team had beaten Sporting Gijon 6-1 and Celta Vigo 5-0.
"We are in the middle of the tie, we have nothing to lose and a lot to win -- if they scored four, we can score six," added the strangely prophetic Barca coach.
PSG's English Twitter feed had just one word to sum up the French club's defeat: "gutted," while its website used the word "speechless" for its headline for a report of the defeat.
In June 2016, PSG's Qatari owners had appointed Spanish coach Unai Emery, who had led Sevilla to three consecutive Europa League triumphs.
The hope was that Emery's tactical nous would help PSG's billion dollar fueled quest to win the Champions League and in the first leg the French club had run ragged a strangely subdued Barca.
Luck certainly wasn't on PSG's side on Wednesday -- Barca's second goal came from a Layvin Kurzawa own goal, Cavani hit the post, while the home side's first penalty derived from Thomas Meunier's slip, causing Neymar to tumble over the Belgian and win a foul.
Even so the French side will be left wondering just how they exited the Champions League given their commanding performance and lead they had established in the first leg.
"I haven't spoken to the players yet, it's not the right time," PSG's CEO and chairman Nasser Al-Khelaifi told the club's website."Everyone is annoyed, it's normal. We're going to calm ourselves down."
"In five minutes, we lost everything," said Emery. "We weren't able to defend. It's an experience. A negative experience, but an experience all the same. I'm learning for the future."
The scenes in the Nou Camp press area looked as chaotic as events on the field, with journalist Reshmin Chowdhury tweeting a video of his astonished media colleagues trying to come to terms with what they had just witnessed -- let alone report it.
"This is a crazy, unique sport," said Enrique after the game. "I dedicate this win to all Barça fans who kept faith in us.
"No one stopped believing," added the Barca coach. "The team were spectacular. We were rewarded in the end."
