The hosts had a two-goal lead before the first half ended, thanks to some poor defending by Gerard Pique and a quality finish by the former Liverpool man.

Every now and then, fans can witness a story just like the one involving David & Goliath. Today, Celta fans may have that feeling after destroying Barcelona with an astonishing 4-1 score. Even though los Blaugranas dominated in such stats as ball possession, Celta made the most out of their chances in front of Ter Stegen's net, capitalizing on mistakes by Pique, and finally handing Luis Enrique's team their first loss of the season.

Just when the first goal by Los Blaugranas seemed to be getting closer, Nolito sent his right-footed shot straight to the post and into the back of the net to start the party for the hosts.

Just four minutes later, Gerard Piqué failed to clear the ball from dangerous ground, leaving it for Iago Aspas to chip the ball into Ter Stegen's net.

After the break, Barcelona tried to get the ball near Celta's goal, but it was Iago Aspas who took advantage of Los Culés sloppy defending to score the third goal on a fast break that started from a corner kick for the away team.

When the game was coming to a close, Neymar made it 3-1 momentarily, but John Guidetti sealed the deal for the hosts with a magnificent finish.

Fans, as always, had a field day criticizing Barcelona's poor defending. Here are some of their best comments.

"And now...a poem"

"Celta Vigo defeated Barcelona 4-1 and everyone be like..."
