Chelsea suffered the heaviest defeat in their Premier League history against Manchester City on Sunday.
Pep Guardiola's side are chasing back-to-back titles and their 6-0 demolition of the Blues proved why some are making them slight favourites to pip Liverpool to top spot.
Sergio Aguero was the star man as he scored a hat-trick, while Raheem Sterling netted a brace and Ilkay Gundogan rounded off the scoring.
It was a day to forget for Chelsea, who really didn't help themselves with some terrible defending throughout the game.
As has happened on a number of occasions already this season, after going behind at City, the team just seemed to give up.
The same theme was present in defeats against Tottenham, Arsenal and Bournemouth too.
WHO'S TO BLAME?
Left-back Marcus Alonso has shouldered much of the blame for Chelsea's defensive struggles this season and arguably, he was at fault for City's first goal on Sunday.
Some fans can't understand why Maurizio Sarri still starts the Spaniard, who was replaced by Emerson after 73 minutes at the Etihad.
But, he isn't the only player that supporters should blame, especially as the entire team were so poor against the reigning champions.
In fact, speaking on Monday, Vinnie Jones picked out another Blues defender for criticism - suggesting that David Luiz goes into hiding when his side are struggling.
LUIZ GOES MISSING
"David Luiz, I think he hides when Chelsea are losing," Jones said on talkSPORT.
"I saw the game and just thought, ‘what is going on here?'
"When Chelsea are winning, he’s pinging 60 yard balls about and looking good, but every time I’ve seen Chelsea struggle or are losing, Luiz will hide. You can't have that."
That's a pretty damning assessment of Luiz and Jones went even further, suggesting that the Brazilian has failed to fill the hole that John Terry left at Stamford Bridge.
"John Terry was a massive hole to fill and he hasn’t done it for me. He really hasn’t."
If Chelsea want to avoid any more humiliating defeats this season, then certain players really need to step their game up - or risk being dropped as Sarri holds an inquest into the team's struggles.News Now - Sport News
