Today's match represents a chance for Barcelona to set things right and start the 2015/16 campaign with much-needed victory after the Supercopa debacle. The only positive from last week's sporting disaster at San Mamés would be the abrupt wake-up call the team received, emphasising the need to guard against complacency after all the talk of the Sextete. Today's opponents, Athletic Bilbao, are very much a personification of what it means to play as a team - with their ferocious team spirit and willingness to lay everything on the line for each other.
These are some battles on the pitch that would be key to kicking off the new season with a win.
