Chelsea produced a second-half surge of four goals in nine minutes to come back from a goal down and beat Bolton.
Stelios Giannakopoulos stunned the home side when he slotted in from six yards but Bolton had no answer as Chelsea burst into life after the break.
Didier Drogba's strike levelled matters before Frank Lampard's shot and free-kick, after Ricardo Gardner saw red for a handball, put Chelsea ahead.
Drogba's shot and Eidur Gudjohnsen's cool finish completed the rout.
Bolton had barely had a touch of the ball before Chelsea had their first chance - Drogba angling a drive narrowly wide.
But the visitors shocked the Blues as they caught the home side's normally watertight defence off-guard.
El-Hadji Diouf slid a cross in between John Terry and Asier del Horno with Giannakopoulos applying the finishing touch by side-footing past keeper Petr Cech.
Chelsea's response saw Del Horno head just wide and Bolton scramble the ball away after a Joe Cole shot was saved by keeper Jussi Jaaskalainen.
Wright-Phillips impressed as he made a rare start for Chelsea
But those two chances proved to be the home side's best in the first half as they struggled with the aerial threat posed by Bolton.
Giannakopoulos then went close as he latched onto a long-ball into the Chelsea box only for his shot to be blocked by Ricardo Carvalho while Gary Speed thundered a half-volley against the crossbar for the visitors.
Midfielder Michael Essien summed up the Stamford Bridge side's frustrations with a dangerous tackle on Tal Ben Haim and was fortunate to escape with a yellow card.
There was more urgency about Chelsea's play after the break and their equaliser came when Drogba was quickest to react after Lampard's free-kick was parried by Jaaskalainen.
And Chelsea powered into the lead when Lampard drove the ball home after Drogba had the presence of mind to produce a clever backheel as he was swarmed by defenders.
Bolton's misery was then compounded when Gardner was red-carded for handball and Lampard scored from the subsequent free-kick.
Drogba converted Lampard's corner with a well-timed near-post strike for his second and Chelsea were proving irresistible.
Gudjohnsen's goal only served to cap an emphatic comeback for the Premiership leaders.
Chelsea boss Jose Mourinho:
"It was a cool meeting at half-time where I had to explain with a lot of attention what we had to do.
"Sometimes when you are winning you have to be tough because they need to be shaken up but that was not the case.
"It was question of bringing something different in tactical terms and what the opponent would not be ready for."
Bolton manager Sam Allardyce:
"We scored so early that it was always going to be difficult to try and hang on.
"Also Essien should have been given a straight red for his tackle on Tal Ben Haim and that was a key moment.
"The referee was right to have sent Ricardo Gardner off but Essien should have gone and that decision cost us."
