Frank Lampard's 200th goal for Chelsea set them on their way to a 2-0 home win over West Ham to boost their Champions League hopes.
Lampard is now two goals behind Bobby Tambling’s all time club record after reaching the landmark against his former side with a 19th minute header to put the Blues in front.
Eden Hazard capped a brilliant individual performance with Chelsea's second on 49 minutes as the Londoners took advantage of Tottenham's 1-0 defeat to Fulham to move up to third in the table.
The result leaves Chelsea in position for a strong finish to a turbulent season as they target a top four place, while they are also in the last eight of the FA Cup and the Europa League.
Against a timid West Ham side, they played with flair and energy, with the visitors particularly unable to handle the vision and trickery of Hazard and Juan Mata as the attacking duo floated in to pockets of space.
The major talking point before kick-off was Rafael Benitez's decision to drop John Terry and Fernando Torres to the bench despite both scoring in the Europa League win over Steaua Bucharest.
The hosts started brightly and should have taken the lead after just six minutes when Lampard played Demba Ba through on goal but the striker miskicked his shot.
Lampard, however, had no such problem in the 19th minute as he netted his 11th league goal of the campaign. The midfielder drifted in between the West Ham defenders and was perfectly placed to head home Hazard's clipped pass in to the net from eight yards.
The only frustration for Chelsea at the break would have been their failure to double their advantage, with Ba guilty of missing their best opportunity when he shot straight at Jussi Jaaskelainen.
But less than five minutes after the re-start, the second goal arrived - and in emphatic style.
Hazard played a delightful one-two with Mata, danced across the West Ham penalty area and, after fooling three defenders by faking to shoot, slammed the ball in to the bottom corner with his left foot.
