Live Text isn't live anymore, this is a record of the match events.
Full Time THERE'S THE FINAL WHISTLE: Three points, three goals, a clean sheet, no injuries and no bookings. Job done.
90
MORRISON CRACKS OVER THE BAR: The resulting effort is not on target, however, and Arsenal will win this one with their clean sheet intact.
90
WEST BROM HAVE A FREE-KICK: It's 30 yards out from goal, and it's unlikely they'll go short with this one.
90
"THREE NIL TO THE ARSENAL": The cry from the Emirates faithful after a truly comfortable outing for the Gunners.
90
THREE MINUTES ADDED ON: Just minutes remaining in this one. Arsenal will be keen for a clean sheet.
90
ARTETA PLAYS IT SHORT: It's to Santos and back to the Spaniard, who clips a neat ball into the box which Foster gathers under pressure.
90
SANTOS WINS A CORNER: It's a late one for Arsenal - can they get a fourth?
88
WEST BROM HUNTING A CONSOLATION: They haven't given up to their credit, and Morrison calls Szczesny into action again with a well-hit effort on target.
87
REID FORCES A GOOD STOP: Is that Szczesny's first save of the game? That's the sign of a good goalkeeper. The right-back powers a header down from the resulting corner, but Szczesny holds on comfortably. Good save.
86
WEST BROM GET A CORNER: Koscielny blocks Thomas' fierce cross and the Baggies get a set-piece.
85
BRUNT'S DELIVERY IS OVER: To summarise West Brom's afternoon, the winger gets into a good position before slipping to divert his cross over.
84
NO BOOKINGS SO FAR: Not wanting to tempt fate, but we've seen a clean game here this afternoon. In truth there hasn't been one opportunity to dish out a yellow today.
83
ARSENAL SEEING THIS ONE OUT: It's been as dominant a performance as you are likely to see from the Gunners. This is the Arsenal we know and love.
81
Substitution DORRANS HEADS OFF: That's all three changes made for both sides now, as young George Thorne comes on for West Brom.
80
IMMENSE FROM VERMAELEN: Tchoyi is played through the middle - he's onside - but Vermaelen slides in early to block the forward's effort. Was it ever in doubt?
80
FRESH LEGS LOOKING TO SHINE: It's an opportunity for the team's fringe men to show what they can do in these last 10 minutes.
78
Substitution ANDREY'S ON: He'll arrive in place of Theo Walcott, who's been involved from the word go this afternoon.

75
GAME, SET AND MATCH: Surely there's no way back for West Brom now? This has been a dominant, assured and enjoyable Arsenal performance. They fully deserve this lead.
75
LOVELY FINISH FROM THE SPANIARD: Van Persie is involved once more, driving forward before laying the ball into the path of Arteta. The summer signing makes no mistake with the finish, firing low into the corner past Foster.
74
GOAL! - Mikel Arteta 3 : 0 THERE'S THE THIRD! MIKEL ARTETA GETS HIS SECOND ARSENAL GOAL!
72
Substitution ....AND ON COMES BENAYOUN: It's Gervinho coming off, who's enjoyed another lively game.
71
Substitution DOUBLE SUBSTITUTION FOR ARSENAL: The first brings Tomas Rosicky into the fray for the excellent Aaron Ramsey.
71
Substitution WEST BROM MAKE A CHANGE: The second one of the afternoon sees Yousouff Mulumbu replace Simon Cox.
70
KOSCIELNY MARAUDS FORWARD: The Frenchman takes it past a West Brom man, strides forward and lays the ball to Van Persie who can't quite return the favour.
69
A FOURTH ON THE CARDS? Arsenal are showing few signs of letting up here. This time it's Tomas Rosicky having a pop at goal, but his powerful strike is blocked.
69
ARSENAL LOOKING FOR A THIRD: The half has opened up now and both sides have enjoyed possession in the other's half.
68
SONG FORCES THE SAVE: It could so easily have been three for Arsenal. Alex Song picks up Gervinho's pass before hitting a lazy effort first time which Foster beats away well.
66
KOSCIELNY HEADS AWAY FOR A THROW: Santos is caught with a poor header which Chris Brunt forces into a cross - but Koscielny is on hand to clear.
65
LOVELY FEET FROM GERVINHO: The Ivorian skips inside a defender, plays a one-two with Arteta and forces Foster into a smart save with a powerful effort on the angle.
64
GREAT BALL IN FROM JENKINSON: The right-back's half is going from strength to strength, this time whipping in a fine ball which West Brom are forced to contend with. Van Persie was close to that one.
63
Substitution TCHOYI COMES ON: In a West Brom change it's Zoltan Gera coming off.
62
WEST BROM LOOKING FOR A LEVELLER: They're trying this half, but Arsenal's backline are remaining stout. Szczesny is yet to make a save in the second period.
60
THAT'S SO CLOSE! Gervinho finds Ramsey with a neat pass into the box. The Welshman switches onto his left foot and drills a fizzing effort just wide of goal.
59
BRILLIANT FROM JENKINSON: Jerome Thomas threatens to break down the right but the young right-back halts danger with a fine sliding challenge.
58
BRUNT SCISSORS OVER: The ball loops down to the Republic of Ireland international, who scissor-kicks high over the bar.
57
JENKINSON ENJOYING THE AFTERNOON: The youngster is playing well down the right side today, linking up well with Walcott all afternoon.
56
QUIET START TO THE HALF: Neither side have created any chances of note. It's suiting Arsenal, but the fans will obviously be keen for more goals this half.
54
SANTOS GETS A FOOT IN: Brunt finds Dorrans as West Brom look to build, but the Brazilian gets his foot in and the Baggies are forced to start again. Dorrans picks it up once more but drags another effort wide.
52
VERMAELEN HEADS JUST WIDE: The Belgian leaps highest from the corner - oddly unmarked - and powers a header just past the far post.
52
MCAULEY FORCED INTO ACTION: Jenkinson's cross into the box is dangerous as it targets Gervinho, but McAuley is there to poke away for a corner.
51
WALCOTT'S CROSS IS WAYWARD: The England winger skips to the byline but puts his cross into the stands.
50
DORRANS SCUFFS ONE WIDE: The Scot attempts the half's opening chance, but drags a tame effort wide of a post.
49
BAGGIES FANS NOT BOUNCING: Instead they are annoyed and keeping quiet in the corner of the north stand.
48
SUBDUED START TO THE HALF: Arsenal are knocking the ball around in midfield nicely once more without threatening. The first half was welcomingly dominant from the hosts.
47
NO CHANGES AT THE BREAK: Both sides go into the second period with the same sides that started the first.
46
WE'RE BACK UNDERWAY: Can Arsenal build on their solid lead in the second half?
Half Time THERE'S THE HALF-TIME WHSTLE: Arsenal go in ahead two goals to the good, and look strong value for their lead.
45
ARTETA FIRES OVER: Arsenal are not done with the half as the Spaniard picks up the ball on the edge of the box before firing over.
45
BUT IT'S POOR: Instead of shooting they look for a cross - but in schoolboy fashion a West Brom man is flagged offside.
45
BUT WEST BROM HAVE A DANGEROUS FREE-KICK: Dorrans and Brunt are over this - they have the ability to threaten from this range.
45
WE'LL HAVE TWO MINUTES ADDED ON: Arsenal will hopefully see this out and take their two-goal advantage into the break.
43
THE FANS ARE LEAVING HAPPY: The half-time pies await for the Emirates faithful. And that beer will taste all the sweeter after this 45 minutes.
42
SOLID FROM VERMAELEN: Brunt propells a driven free-kick into the penalty area, but Vermaelen rises highest to thump away a header. Fine work from the Belgian.
41
A STRONG HALF FOR ARSENAL: It may have seemed a little subdued at times, but this is as comfortable a display as you are likely to see. Arsenal have been clinical and now have themselves a two-goal cushion to work with. But three's a charm, of course...
40
VAN PERSIE THE ARCHITECT: The Dutchman cuts the ball back into the box from a deep cross. Gervinho should probably get on the end of it, but the ball drops loose to Vermaelen who smashes home for goal number two.
39
GOAL! - Thomas Vermaelen 2 : 0 VERMAELEN IS BACK! WHAT A RETURN TO THE PREMIER LEAGUE!
38
JENKINHO WITH THE TURN: Sorry, getting a little carried away here. But Arteta controls nicely and finds the young right-back, who evades Jones with a lovely turn before crossing into the box.
37
WEST BROM COMMENTARY TEAM THINK OTHERWISE: But they're wrong. Sorry chaps.
36
THOMAS LOOKS FOR A PENALTY: It's good play from West Brom in midfield as Morrison finds the former Arsenal man. He goes down under a challenge, but it didn't look like much from here.
34
TEN MINUTES LEFT IN THE FIRST HALF: There's an eerie silence around the Emirates at the moment, somewhat resemblent of the game after Van Persie's opener.
32
ALL QUIET ON THE EMIRATES FRONT: Chances have become few and far between here in north London. There's handbags between Santos and Cox as the Brazilian wins a free-kick for his side.
31
ARSENAL DICTATING: West Brom are seemingly happy to let the Gunners enjoy possession - which they are doing, of course. They can smell blood for a second.
30
MCAULEY DEFENDS NEATLY: The Northern Irishman chests Andre Santos' cross into the hands of Ben Foster. That's good defending from the centre-back.
29
KOSCIELNY DOES WELL AGAIN: The Frenchman slides in with a well-timed challenge inside the box to deny Cox once more.

26
DELIGHTFUL FROM ARSENAL: It's Van Persie to Walcott to Gervinho - but the Ivorian is flagged offside. Arsenal's tails are up and they want two.
25
ARTETA GOES DOWN IN THE BOX: The Spaniard runs into a Baggies defender and the crowd want a penalty - but he's never getting that.
25
CAN WEST BROM RESPOND? They've played reasonably well so far, but they;ve rarely troubled Szczesny. Olsson and McAuley have done their jobs well at the back, but they could do little about Ramsey's passing masterclass.
24
ARSENAL CONTINUE TO PRESS: The goal has certainly not deterred the hosts, as Andre Santos wins a throw. Arsenal pick the ball back up in midfield and look to go again for a second.
23
THAT WAS ALL ABOUT RAMSEY: Just check out the Welshman's ball to Walcott when you can. The pass is delightful, Walcott forces Foster into a save and Van Persie picks up the pieces to tap home.
22
GOAL! - Robin van Persie 1 : 0 IT'S THERE FOR ARSENAL! Of course it's that man Robin van Persie with the goal, but he'll rarely get an easier one.
21
WALCOTT WINS THE THROW: He's been the more active of the two wingers, and wins one in a useful position for Arsenal.
20
WEST BROM PRESSING: Cox is regularly involved whenever the visitors manage to push forward. This time he works it out wide to Brunt, whose drifted cross finds the welcome hands of Szczesny.
19
SZCZESNY TAKES WELL: Chris Brunt drives in a low cross towards the danger zone, but Szczesny dives low and gathers brilliantly.
18
OLSSON IS ONLY JUST BACK ON: The Swede has spent the last few minutes cleaning himself up after his battle with Vermaelen. West Brom survived their brief spell with 10 men just fine...
17
ARTETA STRIDES FORWARD: The midfielder picks out Jenkinson on the right, whose cross towards Van Persie is dealt with well once more.
16
SANTOS SHOWS HIS BRAZILIAN FLAIR: The wing-back wins the ball from Chris Brunt, pirouettes round another before winning a throw. The crowd enjoyed it, anyway.
15
WE'RE BACK UNDERWAY: Olsson will be fine, and Gareth McAuley sportingly punts the ball back to Wojciech Szczesny for the Pole to restart play.
13
OLSSON DOWN: The Swedish centre-back is down clutching a bloodied face after his aerial challenge with Vermaelen. That was brave defending from the Baggies man.
13
VAN PERSIE LOOKS FOR VERMAELEN: The big Belgian is forward for a free-kick, but he's beaten in the air by a West Brom defender and they clear.
12
SANTOS DOES WELL: Ramsey is caught in possession by James Morrison, and Cox is freed through the middle once more. Santos and Vermaelen combine well to retrieve the ball for Arsenal.
11
RAMSEY'S BALL FINDS NOBODY: The Welshman tries to clip a ball into the box, but he slips and Foster sees the ball out comfortably.
10
ARSENAL ON TOP: The visitors have barely troubled the Arsenal backline so far - the Gunners have managed to keep the ball reasonably well.
9
SANTOS CURLS ONE OVER: The Brazilian's free-kick is poor, however, and Row Z sees some action.
8
GERVINHO BROUGHT DOWN: James Morrison is the guilty party here, hauling down the Ivorian 30 yards from goal. Andre Santos is standing over it.
8
WALCOTT FORCES FOSTER INTO ACTION: The England man tries to curl one into the area, but Foster is on hand to hold onto the ball well.
7
EMIRATES IN GOOD SPIRITS: It has the feel of a stadium with a team on the up. Arsenal fans are in confident spirits, and they have every right to be.
6
THOMAS FLAGGED OFFSIDE: Steven Reid attempts to pick out the former youth graduate on the left - but the official's flag is raised once more.
5
JENKINSON WHIPS ONE IN: The full-back's growing reputation from wing positions is something to admire. This one's not the best, but in fairness there aren't too many bodies in the box.
3
LATE FLAG: Cox is played down the left this time and looks like he may be in - but the official's flag is raised late. It was the right decision.
3
GOOD FROM KOSCIELNY: Simon Cox threatens to burst through the middle for West Brom, but the Frenchman is having none of it and gets a foot in before sweeping up neatly.
1
GRIM AFTERNOON IN NORTH LONDON: It's a cloudy one at the Emirates this afternoon, Here's hoping the football here brightens up the day.
1
EARLY SHOT FROM VAN PERSIE: The captain gathers Walcott's ball in from the right, swivels and sees his shot inside the box blocked well to safety.
1
AND WE'RE OFF: Arsenal get us underway at Emirates Stadium this afternoon.
MINUTE'S SILENCE IMPECCABLY OBSERVED: With remembrance Sunday just around the corner, both sets of fans are noble enough to respect the moment.
WEST BROM PLAYING FIVE IN MIDFIELD: As usual it could be a tough afternoon for Arsenal, and they may well need some patience. West Brom are a useful side, but the five-strong midfield may be a tough nut to crack.
AND HERE THEY COME: The teams head out onto the hallowed turf at Emirates Stadium, Arsenal lead once more by Van Persie.
IT'S A NEW PARTNERSHIP AT THE BACK: Laurent Koscielny, so strong in recent weeks, is back in the side. And it'll be Thomas Vermaelen alongside the Frenchman. This should be interesting.
WHO WILL MAKE THE DIFFERENCE TODAY? In recent weeks it's been Robin van Persie stepping up to the mark in style. But of course, he's not done it alone. Gervinho and Aaron Ramsey have been particularly impressive in recent weeks.
THE WONDER OF YOU RINGS OUT: It's that time of the afternoon already, we're 10 minutes away from the whistle at Emirates Stadium.
ROBIN GETS HIS AWARDS: The skipper was named Barclays Player of the Month yesterday, and also picks up his trophy for Arsenal.com's fans' poll. You just can't argue with it can you?
CAN ARSENAL BUILD ON THEIR FORM? Victory would undoubtedly provide another stepping stone on the way to redemption for Arsene Wenger's side - and could see them leapfrog Liverpool depending on the result from Anfield today.
