Barcelona significantly strengthened their chances of winning a 26th La Liga title after destroying fierce rivals Real Madrid in El Claisco.
Philippe Coutinho got the hosts off to a flyer after 11 minutes and they doubled their lead through Luis Suarez 20 minutes later.
Marcelo pulled one back for Madrid five minutes into the second half but that was as good as it got for the visitors.
Suarez completed his hat-trick after scoring twice more in the space of eight minutes, before Arturo Vidal came off the bench to head home and seal an emphatic 5-1 win for the Catalonians.
The result only compounds Madrid's misery at the moment.
Julen Lopetegui's side are now ninth in the table having only picked up 14 points from their opening 10 games.
They've won just four times in the league so far this season and now Lopetegui is believed to be on the brink of losing his job.
Casemiro gave a rather brutal, yet honest assessment of Madrid's season so far, branding their opening few months of the season as a 'disaster'.
"It's not just about attitude or tactics: it's everything," said Casemiro in his post-match interview, per Marca.
"The players have got to run more, fight more. This 5-1 result pretty much sums up our season so far. It's been a disaster because we're all playing poorly."
But it seems that not everyone in a white shirt feels the same way.
Ramos took exception to his teammates comments when asked about them in the mixed zone, describing them as 'inopportune.'
"It's inopportune to say that," he said when asked about Casemiro's comments, per Marca.
"We must remain calm. It's not the time to point the finger at anyone. We have to be self-critical and sometimes it's the players' fault."
Fair play to Casemiro for speaking his mind after the game, but you've got to agree with Ramos.
Madrid are struggling in the league and he should be working hard to improve their league position rather than slating the team in the media.
Los Blancos are now seven points behind Barcelona in the race for the La Liga title and will have it all to do if they are to catch up with their fierce rivals.
