West Ham United 0-3 Chelsea
Barclays Premier League
Frank Lampard returned to haunt his former employers once again on Saturday as his double helped Chelsea to a 3-0 win over West Ham United at the Boleyn Ground.
Lampard struck from the spot midway through the first half to give the Blues a lead they never looked like relinquishing, particularly once Oscar quickly doubled the advantage.
The Hammers were never able to impose themselves on the contest and Lampard deepened their woes with a clinical finish eight minutes from time.
The defeat leaves West Ham fourth from bottom of the Barclays Premier League table with crucial fixtures against Fulham and Crystal Palace next on the horizon.
The opening exchanges were fairly even and West Ham almost found a route to goal on 18 minutes when Guy Demel stepped in to win possession on halfway and send the ball out to Stewart Downing. The winger's cross was instant and directed towards Kevin Nolan, whose header back was blocked, and Joe Cole's shot on the rebound was also snuffed out.
Three minutes later and Chelsea were in the lead thanks to a goal of the Hammers' own making. Guy Demel was left with his head in his hands after attempting to guide the ball back to Jussi Jaaskelainen with his thigh.
The pass was underhit and Oscar nipped in to draw a foul from the goalkeeper. Lampard stepped up and smashed his spot kick high into the roof of the net to set his side on their way.
A minute later the former Hammer could have made it two when Joey O'Brien was caught in possession and Oscar passed square for Lampard, whose swept shot was gathered by Jaaskelainen.
There was no such let off with 34 minutes on the clock though, as Chelsea showed great incisiveness to double the advantage. James Collins was attracted to the ball as it was passed into Eden Hazard's feet, leaving Oscar to pick up from his teammate's flick, make his way to the edge of the box and slot the ball into the bottom left corner.
Hammers boss Sam Allardyce responded by introducing Mo Diame and Modibo Maiga from the bench, but still Chelsea found space to hurt the hosts and Samuel Eto'o brought a flying one-handed save from Jaaskelainen with an angled shot which was headed for the top right hand corner.
The second period started in much the same vein and Chelsea were so close to a third on 58 when Lampard's header was met by a Gary Cahill header which Mark Noble cleared off the line.
Moments later the visitors countered with devastating pace, with left-back Cesar Azpilicueta bombing on down his flank to cross for Oscar, who should have done better with his shot at the far post, which flew wide.
For all Chelsea's dominance, the Hammers still had a golden chance to get themselves back in the contest on 65 minutes when Demel somehow wriggled clear of the attentions of two defenders in the corner and cut back for Maiga, whose left footed touch sent the ball wide when a more solid connection would surely have seen the net bulge.
Chelsea made use of their let-off by finally sealing the points eight minutes from the end when Lampard drilled home from the edge of the box after Hazard's blocked shot fell perfectly for his right-footed effort.
