Chelsea hit Wigan for six
Wigan had no answer to Chelsea's goalscoring machine as Carlo Ancelotti's side ran out 6-0 winners for the second game in succession.
Nicolas Anelka and substitute Salomon Kalou each bagged a brace, sandwiching one apiece from Florent Malouda and Yossi Benayoun.
It leaves Chelsea sitting pretty at the top of the table and the Latics propping it up, and with the possibility manager Roberto Martinez may now be fearing for his job.
However, for the opening half hour Wigan's performance in contrast to a week ago was as different as night and day.
However, Chelsea are not champions for nothing and in the 33rd minute they underlined why.
It was simple, incisive stuff as Didier Drogba and Ashley Cole combined down the left to tee up Frank Lampard for a close-range prod that was brilliantly tipped away by captain Chris Kirkland but Malouda's reactions were quick as he tapped home the rebound.
Chelsea doubled their lead after the break courtesy of a crisp, clinical strike from Anelka. After 52 minutes the Frenchman grabbed his second, nodding in from close range after good work from Malouda and Drogba.
James McCarthy saw a deflected effort hit the right-hand post, with Mauro Boselli flagged offside after tapping home the rebound.
Chelsea were not done and after being on the pitch eight minutes after replacing Malouda, Kalou made it four in the 78th minute.
Chelsea rubbed further salt into Wigan's wounds with Kalou making it 5-0 in the 89th minute and fellow sub Benayoun adding the sixth.
