Full-time: Arsenal 2-0 West Bromwich Albion
All over at the Emirates! Alexis Sanchez has proven to be the difference in what was an eye-catching display from the Gunners.
Arsene Wenger will feel pleased with his team tonight, even if they didn't score the goals to underline their dominance.
Arsenal fans have just been informed about transport troubles on the London underground and are now making their way towards the exits prematurely. They've seen enough.
The official attendance, our of interest, is nearly 60,000. There are, of course, not that many people inside the stadium, but the umbrella figures includes people who have paid for tickets and chose not to attend.
We're in added time.
The Gunners are playing a bit of keep-ball at the moment. Both sides seem to have accepted their fate in this game a long time ago. It is drifting towards a rather predictable result.
Arsenal are preparing to make another couple of switches, with Theo Walcott and Joel Campbell getting themselves sorted on the touchline.
Walcott has five minutes to make an impression - and impress England boss Roy Hodgson. Mesut Ozil and Alexis are both making way.
Right, here we go... Arsenal make their first change. The increasingly-impressive Alex Iwobi makes way for Francis Coquelin.
A like-for-like change, as they say.
As a reminder, if West Brom lose this game, it will be just one point from a possible 15 for the Baggies. Thankfully for Tony Pulis, they have already reached the magical 40-point mark.
Elneny is back with us, by the way, and there are only ten minutes left in the game.
It's still slim pickings for Saido Berahino despite the introduction of Rondon. The outspoken forward has had no service to speak of this evening.
The atmosphere is almost eerie at the Emirates. This is a very subdued affair in more ways than one.
Elneny is down at the minute, holding his lower back. That might prompt the Arsenal manager into action.
Some 20 minutes left at a subdued Emirates Stadium. Surely Arsene Wenger must be considering making a change?
If you missed the news earlier, Theo Walcott is on the bench again this evening - I wonder if he'll still be at Arsenal next season?
Ozil appears certain to make it 3-0 after being played in by Alexis Sanchez, but Ben Foster makes a cracking save.
And moments later, the German star's goal-bound effort is blocked by a defender. Ozil denied twice in the space of a minute.
Tony Pulis makes his third and final change for the Baggies with more than 20 minutes still to play.
James McClean makes way for Craig Gardner - can he make a difference in the remaining minutes? We're about to find out...
Another penalty appeal for Arsenal, and it looks like another dive. There is a modicum of contact on Elneny, but it wasn't enough for him to fall so theatrically.
It needs to be said that there is a very strange atmosphere at the Emirates at the moment.
The crowd - which is by no means packed - seem to be paying negligible attention to the action on the pitch as the result seems inevitable.
Alex Iwobi goes down in the box, looking for a penalty. All eyes turn to ref Jon Moss, but he waves away the appeal. A good decision on this occasion.
An hour gone at the Emirates, and Arsenal look to be cruising towards a home win. Perhaps it's time for Arsene Wenger to consider some changes?
Aaron Ramsey - who has been returned to the starting line up tonight - makes an excellent last-ditch tackle to save his team.
The Welshman has made a pleasing comeback, even if he is unlikely to play the whole 90 minutes.
James McClean gets his head on a cross but Petr Cech is able to save without too many problems. Some encouraging signs for the Baggies in the early moments of the second half, though.
The half-time switch means Saido Berahino ought to have more support in this second period. The controversial forward cut a very isolated figure in the opening 45 minutes.
Clearly Tony Pulis was not happy with what he witnessed in the first half and so he is making a change. A couple of changes, in fact.
Half-time: Arsenal 2-0 West Bromwich Albion
It's been the Alexis Sanchez show at the Emirates. The Chilean has a brace and has been at the centre of most of Arsenal's best moves.
West Brom have struck the bar and had a good penalty appeal waved away, but Arsenal deserve their two-goal advantage.
Nacho Monreal almost makes it three after a flowing team move. It all stemmed from some jaw-dropping skills from Mesut Ozil, who appears determined to match Alexis' efforts.
On this occasion, though, the German's final ball is just out of Monreal's reach.
Less than five minutes to go until half-time, and Alexis has been brilliant so far this evening.
The Chilean looks to be back at the top of his game and is leading Arsenal to an important Premier League win as things stand.
GOAL: Arsenal 2-0 West Bromwich Albion (Sanchez)
Arsenal and Sanchez have a second! The Chilean - who has been sensational so far this evening - nets his second from a free-kick.
From the edge of the box, the eye-catching forward whips the ball low into the corner of the net, with Ben Foster's view obscured by players in the wall.
This has been too easy for the Gunners.
Ben Foster almost makes a major error. Well, in truth, he did - but the West Brom keeper just got away with it, after allowing a goal-bound effort to pass through his legs.
Thankfully for Foster, there were defenders behind him on the line.
