Everyone connected with Barcelona will remember their Champions League loss to Liverpool last season for many, many years.

After beating the English side 3-0 in the first leg, Barca looked almost certain to progress to the final.

All they needed to do was make sure they didn't get humbled at Anfield.

Although they were 1-0 down going into the break, they were still in a commanding position to make it to the final.

But they completely crumbled in the second half. They conceded three quick-fire goals in the final 45 minutes to lose 4-0 on the night and exit the competition.

Barcelona players looked stunned on the pitch at full-time.

And, in some brilliant footage captured by Barcelona's new documentary 'Matchday', they looked equally as stunned in the dressing room after the game.

A clip from the documentary shows Barca players sitting down in the dressing room in stunned silence.

No one speaks a word for 45 seconds. A number of Barcelona players are shown, including Gerard Pique, Jordi Alba and Marc-André ter Stegen.

All of which just look around aimlessly in sheer disbelief. It really is a great clip.

One football fan has decided to use 'Mad World' by Tears for Fears over the footage and it makes it even better.

'The tears are filling up their glasses, no expression, no expression'. That music is perfect for the clip.

Another football fan has used 'The Sound of Silence' by Simon & Garfunkel and that also makes the footage even better.

Incredible. It took six months for footage from the Barcelona dressing room that day to emerge, but it was well worth the wait.
