Barcelona have been widely panned in the Spanish papers on Sunday morning after falling to a shock defeat against minnows Cadiz.
The setback, already the club's fourth loss of the LaLiga season, sparked Ronald Koeman to savage his players and question their attitude as they dropped just three points above the relegation zone.
And both Sport and Mundo Deportivo have since highlighted the manner of the sloppy errors which led to their painstaking downfall.
Former Manchester City striker Alvaro Negredo netted the memorable winner for the newly-promoted hosts just 44 seconds after being substituted on.
The 35-year-old was able to pounce on horrific and hesitant defending from the Nou Camp giants to close down Marc-Andre ter Stegen, round Frenkie de Jong and finish into the unguarded net.
Alvaro Gimenez fired Cadiz into the lead on eight minutes, with Pedro Alcala's own goal proving a mere consolation for Barcelona.
The front page of Mundo Deportivo has been emblazoned with the headline 'Fatal Mistakes' in unmissable white text. A photo of a handful of Catalan stars, including the visibly frustrated Lionel Messi, features on the cover.
Youngster Oscar Mingueza, handed a start again due to a raft of injuries in central defence, was guilty of making an early error for Gimenez's opener.
His more experienced team-mates, namely Ter Stegen, Clement Lenglet and Jordi Alba, also delivered errant and error-strewn performances.
Sport, meanwhile, opted for the headline: 'Go Blunder!'. The publication also led their coverage on the mistakes that ultimately compounded another miserable afternoon for Barcelona.
Ronald Koeman's side fell to eighth in the standings and are already 12 points adrift of league leaders Atletico Madrid.
The Dutchman, who was hired in the summer to replace Quique Setien, did not hold back in lambasting his players in his fiery post-match press duties.
He said: 'The defeat is difficult to explain. We've come here after some good games, but the first half wasn't good.
'We were better in the second half, but the way in which we lost was incredible. We lost due to an unexpected mistake that you cannot make.
'It came from not being focused. The attitude wasn't good tonight, and not just from the defenders.
'It's very hard to explain some of the goals that we've conceded. I think it might be because of a lack of concentration.
'We lack aggression without the ball. That might be why we concede. It's not easy to explain that second goal.'
