London: Chelsea held off a stirring second-half fightback by London rival Arsenal to claim a 2-1 win on Sunday, tightening its grip on third place in the Premier League. Early goals from Juan Mata and Frank Lampard put the home side in complete control but Theo Walcott's brilliant 58thminute strike gave Arsene Wenger's team hope.
However, with the snow tumbling down, Chelsea were able to avoid a repeat of the midweek fixture here against Southampton by not letting slip a two-goal lead.
It enabled Rafael Benitez's team to take a firm grip on third place and establish clear distance between themselves and Arsenal, who limped to their second consecutive league defeat after losing to Manchester City last weekend.
Wenger's side showed heart and fight to make a game of it in the second half but they were ultimately made to pay for a feeble first-half showing in which they were comprehensively out-played and out-thought by the hosts.
Chelsea were so fluent and dominant in the early exchanges that the home support forgot to continue their 16th-minute tradition of chanting the name of Benitez's predecessor Roberto Di Matteo.
It was enough to leave those who did not take up their seats because of the snow that tumbled down in west London all day and throughout the match kicking themselves with envy.
Early on, Olivier Giroud wasted a great opportunity to put Arsenal ahead after being put through by Walcott, and Chelsea immediately made the visitors pay for the let-off.
The home side broke up the field, Cesar Azpilicueta delivered an excellent cross-field pass to Juan Mata, who pulled the ball down with a wonderful first touch and hammered it into the net with his second. The Spaniard was in sensational form, orchestrating Chelsea's clinical attacks with his touch, vision and gift for finding space.
Ramires and Eden Hazard were only marginally less influential and Arsenal's powderpuff defence, offered precious little in the way of protection, could not cope.
After 15 minutes, the visitors were sliced open once again after Abou DIaby was robbed of the ball in the middle of the park. Mata found Ramires in acres of space in the penalty box, the Brazilian dawdled before being falling over Szczesny's outstretched leg and Chelsea were awarded their eighth spot-kick of the season.
Szczesny, who had cover from his defenders, escaped with a yellow card but could not prevent Lampard converting the 47th penalty of his Chelsea career.
From then on, it was one-way traffic throughout the opening period. Arsenal's frustration was encapsulated by an animated Jack Wilshere, who, isolated in an advanced attacking midfield role, could not get the ball and made no attempt to hide his disgust at his team-mates' failure to treat their passing with care.
The visitors were much improved after the break, creating three good opportunities before Walcott sprung the Chelsea off-side trap after 58 minutes.
Santi Cazorla threaded the ball through to Walcott, who opened up his body to fire it magnficently past the grasp of Petr Cech to give his team a life-line.
With Wilshere increasingly influential and Walcott a constant threat on the right, Arsenal looked the better team. However, Wenger made his feelings clear about the effectiveness of his central midfield by subbing both Coquelin and Diaby.
Despite their late rally, Arsenal could not find a way through a Chelsea defence that was far more resilient than it had been against Southampton on Wednesday.
