FULL TIME. Chelsea cling on for the win as they secure a much-needed home victory. Goals from Mata and a penalty from Lampard prove enough to beat Arsenal, who battled well in the second half, with Walcott scoring.

Wilshere now with a cross into the box but Giroud's header spins up and onto the roof of the net. That could be it.

Another corner for Arsenal as the pressure continues...

Cech punches away under pressure and when Arsenal pump the ball back into the box, Cahill makes a crucial tackle with Walcott ready to pounce.

Late corner for Arsenal... but Ramires heads away for another.

Stat from Infostrada: "This season, Arsenal have scored nine goals in the final 10 minutes of PL matches – the most in division with Manchester United."

We will have five minutes of added time.

Up the other end, Walcott lays the ball off to Giroud and he tries to surprise Cech with a quick effort from 35 yards. However, it skids into his arms.

A free-kick is cleared out to Bertrand and he fires in a fierce effort that is blocked by Sagna. It hit the top of his arm/torso.

A change for Chelsea as Marko Marin replaces Hazard, who has faded alarmingly.

Vermaelen takes charge of the set-piece but goes for the far corner and can't get the necessary bend on the balll.

Cole trips Sagna right on the edge of the box and Arsenal have a free-kick in a good position. He goes into the book.

Ba threatens to turn away from Gibbs and wreak havoc in the box but Gibbs puts in a superb challenge.

Huge chance for Chelsea! Ba breaks free down the left and Szczesny makes the wrong decision to race off his line and leave himself stranded. Ba rounds the keeper, cuts inside but then sees his firm low effort cleared off the line by a superb block from Vermaelen.

The Chelsea fans approved of that decision by Benitez at least. Meanwhile, Arshavin tries to find his way past his marker on the edge of the box but loses possession.

Here comes the change as Ba replaces Torres, of course.

Ba is now stripping off on the sidelines...

Wilshere looks unimpressed and it should have been a foul - Ramires deliberately put his arm in his face after all.

Ramires breaks away after catching Wilshere in the face and pulls out a succession of stepovers before finally being denied by a fine saving challenge from Vermaelen.
