The worrying thing about this abject 2-0 defeat to Granada from the Blaugrana's perspective is that it wasn't the least bit surprising, goal.com reported.
The host hadn't beaten Barca since 2014 but its coach on that occasion, Lucas Alcaraz, was rightly confident that his former club would trouble the Catalans, who arrived in Andalusia on the back of a fortuitous midweek draw at Borussia Dortmund in the Champions League.
“I would not like to be in Barcelona’s position because it played a tough match on Tuesday and is now coming to play a team which is in form and at home," Alcarez quite rightly pointed out on Radio Marca.
Barca, by contrast, has been in dreadful form on the road of late, as coach Ernesto Valverde admitted beforehand.
"When we are away from home, our level of effectiveness and possession decreases," he said on Friday.
"It is costing us in that we are not getting the results we expect when playing away.
"Everything we have been doing well at home we forget to do away. We want to change this. We must be more forceful and decisive."
They were neither at Granada, which has gone top with this fully deserved win. With Messi still nursing his way back to full fitness, the Argentine was forced to start on the bench.
As a result, Barca was utterly devoid of ideas in attack during the first half, despite having Luis Suarez and Antoine Griezmann on the pitch.
Barca was even worse at the other end of the field and, again, that was not in the least bit surprising.
Tuesday's scoreless draw at Dortmund was the only game so far this season in which Barca has kept a clean sheet.
The Spanish chammpion conceded a disgraceful nine goals in just five outings in La Liga, which only serves to underline that Barca should have spent its summer pursuing world-class defenders rather than spending €120 million (£106 million/$132 million) on Antoine Griezmann, who still looks out of place in the Blaugrana attack and has yet to register a single shot on target away from home this season.
Of course, the Catalans did sign a left-back, in Junior Firpo, but it was his horrendous error that led to Ramon Azeez opening the scoring after just two minutes of play.
Messi and Ansu Fati were introduced at the break, in place of the hapless Firpo and Carles Perez, but, in truth, the visitors never looked like drawing level. They hit the target just once all game.
It was Granada which continued to carry the greater attacking threat until the end of the game, although, in the end, it was ultimately grateful to Barca for another gift midway through the second half when Arturo Vidal handled in the area shortly after coming on.
Another substitute, Alvaro Vadillo, converted with aplomb and, even with 24 minutes left on the clock, a 2-0 lead was always going to be sufficient against a Barca side that is horribly unbalanced both in midfield and attack, and handicapped by a pitifully brittle backline.
Naturally, the Catalans looked to Messi in the final quarter to bail them out of jail, as he has so many times before, but there was nothing the barely match-fit forward could do.
Barcelona hasn’t just forgotten how to play away from home. It has also forgotten how to defend.
The only thing this game reminded Barca of is just how desperately reliant it is on its skipper.
