A second-half brace from Josh King and goals from David Brooks and Charlie Daniels added up to a miserable Chelsea outing at Bournemouth.
Josh King's brace inspired Bournemouth to a 4-0 victory as Maurizio Sarri's lacklustre Chelsea suffered back-to-back Premier League defeats.
Cup triumphs over Tottenham and Sheffield Wednesday suggested Sarri's withering assessment of the 2-0 loss to Arsenal had the desired effect, but a section of the away supporters turned on their Italian coach at the Vitality Stadium.
Wales winger David Brooks created King's 47th-minute opener before coolly doubling Bournemouth's advantage, although he pulled up on a subsequent attack to cut a wonderful display short.
