Bournemouth 4 Chelsea 0
Joshua King scored a brace as Bournemouth thrashed Chelsea to knock the Blues out of the Premier League's top four.
A well-deserved and memorable 4-0 win was secured with all four goals coming in a rampant second-half display for the Cherries, with Blues boss Maurizio Sarri receiving flak from the travelling support.
King struck either side of setting up David Brooks before Charlie Daniels headed in a last-gasp fourth which saw Chelsea drop to fifth, below London rivals Arsenal on goal difference.
The defeat was Chelsea's third in a row on the road and Sarri's decision to haul off Premier League debutant Gonzalo Higuain after Brooks' strike was met with disdain from the visiting fans.
Blues supporters will also be demanding an explanation as to why Callum Hudson-Odoi was omitted from their matchday squad altogether.
The 18-year-old travelled to the south coast but was left out of the panel a week after handing in a transfer request amid ongoing interest from Bundesliga giants Bayern Munich.
Bournemouth manager Eddie Howe said: "That has got to be up there (as one of my best results). It was a big night for us, and it is great to do it here in front of our own fans."
On David Brooks' marking of Jorginho, he added: "It was something we looked at and planned and David did a brilliant job beyond his years with his diligence, and then he showed his class at the other end as well, so I'm pleased for him.
"We have always been known for our attacking play but our defensive play needed looking at. We had long periods without the ball so full credit to all of our players. Artur Boruc was superb and his save very early in the match was world class.
"It is a good place to be but we have high standards and high expectations. The wins are the most important things and we are very pleased with how our season is shaping up. It has been a good night. Chelsea did well, Boruc made some world class saves. We built on that and in the end scored some wonderful goals."
That Boruc stop from Mateo Kovacic was one reason why the sides went in level at the interval but it took just two minutes after the restart for Bournemouth to hit the front.
Ryan Fraser got in down the left and played in Brooks, who squared for King to power in his seventh goal of the campaign.
The hosts seemed more than happy to soak up pressure and hit Chelsea on the break - and it was through that method that they doubled their lead.
David Luiz cheaply lost possession by passing straight to Brooks before a weak challenge on King allowed the Norway forward to return the favour from earlier in the half, slotting a pass to Brooks, who coolly found the net.
The young Welshman had been superb for the hosts but limped off with a quarter of the game remaining to be replaced by Jordon Ibe - but it did not stop Bournemouth adding to their lead.
Liverpool loanee Nathaniel Clyne's perfectly-weighted through ball set Junior Stanislas away and he squared for King to tuck home and kill off any lingering threat of an unlikely Chelsea comeback.
Boruc saved well from Cesar Azpilicueta's header but it was Bournemouth who were celebrating again as Daniels headed in from a short-corner routine on the stroke of full-time.
