Chelsea demonstrated the full extent of their attacking power with a thrilling 6-3 win over Everton at Goodison Park.
The victory, in which Diego Costa opened and rounded off the scoring, made it three wins in three in the Barclays Premier League for the Blues and was even sweeter given it came after Manchester City had suffered a shock 1-0 home defeat to Stoke earlier on Saturday.
Jose Mourinho's side got off to a flying start, with strikes from Costa and Branislav Ivanovic putting them two up after three minutes.
Kevin Mirallas pulled one back on the stroke of half-time before a crazy period of five goals in 11 second-half minutes as Chelsea pulled clear only to be pegged back.
Seamus Coleman's unfortunate own goal after 67 minutes made it 3-1, only for Steven Naismith to finish neatly two minutes later.
Nemanja Matic's low strike had Chelsea 4-2 up in the 74th minute, but two minutes after that Samuel Eto'o, on for his Everton debut off the bench, headed home his side's third against his old club.
Ramires stabbed Chelsea's fifth past Tim Howard a minute later and Costa finally put the result beyond doubt in the 90th minute, rounding Tim Howard to score.
