The Catalans will hope to keep their sextuple hopes alive on Monday by producing the greatest comeback in their history, but the odds are stacked firmly against them.
The noises are positive. Barcelona boss Luis Enrique and several of his players have issued rallying cries ahead of the Spanish Supercopa second leg against Athletic Club on Monday night - but the Catalans have never come back from four goals down in their entire history.
Barca was well beaten at San Mames on Friday night as a stunning strike from Mikel San Jose and an Aritz Aduriz hat trick condemned the club to its worst domestic defeat in eight years.
