Barcelona threw away a 3 goal lead in 25 minutes

When Barcelona take a 4-1 lead in the second half of a game, it's assumed said game is over. Even in a glorified friendly, against a good opponent like Sevilla, they're supposed to hang onto that lead fairly comfortably. Instead, they conceded three times in rather quick succession.

Here's Sevilla's goal to make it 4-4, with a pair of subs (and new arrivals) embarrassing Barca's defense. Ciro Immobile turns Marc Bartra into a turnstile, then Yevhen Konoplyanka finishes it off.
