(CNN) -- Chelsea got their charge for the English Premier League title back on track with an emphatic 5-0 win at bottom club Portsmouth.
Didier Drogba and Florent Malouda each scored two and Frank Lampard added another as Chelsea eased the pressure on their Italian coach Carlo Ancelotti.
Drogba's opener on 32 minutes owed much to an error from England goalkeeper David James, who missed his kick when attempting to clear a backpass, allowing Drogba to tap into an empty net.
Frenchman Malouda got his first when he latched onto a pass from Frank Lampard just after halftime, and he grabbed his second ten minutes later after James parried Lampard's shot.
Drogba went clean through to notch the fourth before Lampard sealed the rout with a late header.
The victory takes Chelsea into second place, one point behind league leaders Manchester United.
