Barcelona fans want Ernesto Valverde to be sacked after the La Liga giants lost to Granada on Saturday night.
The Catalan giants went to Estadio Nuevo Los Carmenes looking for a first away win of the season across all competitions.
But they were one goal down inside 65 seconds as they conceded their fastest goal in the league since 2011.
Though Lionel Messi came on at half-time, alongside teenage wonderkid Ansu Fati, Barca could not engineer a comeback.
Instead another substitute, Arturo Vidal, gave away a penalty just after the hour mark which Alvaro Vadilla duly dispatched.
The Catalan club could not even get themselves on the scoresheet despite Messi seeing plenty of possession.
Barca slumped to their second defeat inside just five games and sit seventh, with Real Madrid boasting a game in hand and already having a one-point advantage on their El Clasico rivals.
And following a sluggish start to the season, having also produced a drab performance in their Champions League draw with Borussia Dortmund in mid-week, supporters at the Nou Camp have had enough.
“Barcelona no sign of consistency in passing nor attacking. Simply horrible. Valverde can you please just quit #GranadaBarca,” reacted one on Twitter.
Another wrote: “If Valverde has any shame left, he’ll resign tomorrow.”
“valverde OUT,” a third said simply.
One more tweeted: “It’s over. Mr Valverde Out !! #VALVERDEOUT.”
“If you’re still defending Valverde at this point, I feel sorry for you,” wrote another disgruntled fan.
Another said: “He needs to leave, else we will just be living on past glories.”
“Only Valverde could make a team with Messi, Griezmann and De Jong look this bad,” said one fan.
One touched upon Manchester City’s 8-0 thrashing of Watford in the Premier League, with the Citizens managed by former Barca boss Pep Guardiola.
“Watching Valverde’s Barca after that Guardiola masterclass today is the biggest torture one can suffer,” they said.
One more fan fumed: “Worst coach ever in the history of Barcelona #ValverdeOut.”
“Valverde is a useless coach who is Clueless and senseless,” responded another.
One more posted: “Valverde is a simple man, he’s sits down, choses his team at random, leaves his tactics to the football gods and at the end of the day Lionel Messi decides in exactly which minute he’s going to save us.”
Barcelona will hope to return to winning ways at home to Villarreal on Tuesday (8pm).
By then, they could be as many as five points off of top spot if Sevilla beat Real Madrid on Sunday night (8pm).
