That's it for the live commentary tonight. Thanks as always for joining me, there's plenty more midweek football coverage here on Bleacher Report on Thursday so look out on the website for live action from the Africa Cup of Nations (Ghana vs. Mali) and the Spanish Copa del Rey (Malaga vs. Barcelona).

Plenty of great goals tonight for you so hopefully tomorrow will bring more of the same.

Thanks again and see you soon!

Full time from the Emirates Stadium

Arsenal 5 (Podolski, Giroud 2, Cazorla, Walcott)

West Ham United 1 (Collison)

MOTM: Lukas Podolski.

The long-overdue full time whistle finally sounds, and Arsenal have smashed West Ham all over the show here. Having taken the lead early on through Jack Collison's great strike, the Hammers were pegged back just a few minutes later via an equally impressive effort from Lukas Podolski.

The German was instrumental in a devastating 10-minute spell after the break as quick-fire goals from Olivier Giroud, Santi Cazorla, Theo Walcott and Giroud again opened up a chasm in the scoreline.

A nasty injury to Danny Potts required a lengthy stoppage and hospitalisation for the West Ham youngster, but the game was over as a contest by that point.

Full time at the Emirates Stadium

Arsenal 5 West Ham United 1

90+12'—Final seconds of a long game, which Arsenal take a much-deserved three points from after their blistering start to the second half.

90+10'—We''ve played 100 minutes now at the Emirates. Oxlade-Chamberlain is looking energetic and enthusiastic, but hasn't been able to find any end product yet. Andre Santos hasn't looked energetic, and shoots about 20 yards wide from 30 yards out.

90+9'—Diame and Demel battle away down the right as West Ham earn a reprieve from their defensive duties. The move ends with a goal kick after Demel is overly ambitious in his attempts to take on Aaron Ramsey.

90+7'—Still all Arsenal. West Ham have nine players in their area, and one just outside it. Oxlade-Chamberlain shoots from range, but it's well over the bar. Just blow the whistle, ref.

90+5'—Walcott has a chance—but O'Brien makes a good headed block from the shot.

90+4'—Injury time is apparently taking place exclusively inside West Ham's penalty area. More last ditch defending from the Hammers, as if it makes any difference now, and Wilshere can't get a shot away in time.

90+2'—Madness from Jaaskelainen, who tries to dribble the ball out and passes it straight to Walcott, but his shot is saved by the keeper.

90'—You know, if West Ham can finish the second half the same way Arsenal started it, they could still snatch an unlikely point here.

TWELVE minutes of added time to be played.

89'—Worth noting that West Ham's goal difference is down to minus seven now. Not as bad as Norwich, but certainly rather worse off than they were before the game tonight.

87'—Fox Soccer report that Potts is being taken straight to hospital and is still unconscious. Not a great day all-round for West Ham.

86'—West Ham get the ball into the Arsenal area, but Tomkins is slow to react and is called offside. Four minutes of normal time left.

83'—Back underway then. Interesting to see how much of that injury time the referee adds on; West Ham clearly aren't getting back into this game and it was a very long stoppage.

81'—We've had close a 10 minute stoppage for this severe injury to Potts, who is only now being lifted off the field. Plenty of applause for him as he leaves the pitch...but it doesn't look as though he'll be back on one any time soon.

Elsewhere, don't forget the second League Cup semifinal is going on tonight. Bleacher Report have live coverage of that too, just here, but it doesn't look like it's going to extra time—it's still 0-0 there, which has Swansea heading to the final 2-0 on aggregate.

77'—Potts just being put on the stretcher now having been given an oxygen mask and been strapped up heavily. Obviously a lot of concern for the youngster.

That's not very nice!

It's settled down a bit at the Emirates. Andre Santos has come on as the ultimate insult to West Ham. Follow it LIVE! bit.ly/XYwNDd

74'—We have a break in play at the moment as West Ham sub Daniel Potts is down and needing fairly extensive treatment. He is going to be stretchered off, and the Hammers will see out the game with 10 men.

Arsenal sub: Alex Oxlade-Chamberlain on for Olivier Giroud.

That move will presumably see Theo Walcott go central.

70'—Well, I did tell you before half time that the game had more goals in it.

Arsenal sub: Lukas Podolski off, Andre Santos on.

West Ham sub: Ricard Vaz Te off, Mo Diame on.

68'—Big news...West Ham have the ball near the Arsenal penalty area. Noble's free kick hits the wall and the home side break. What on earth the Hammers are thinking only Sam Allardyce must know, but Arsenal have four on one at the back...but Walcott's cross hits the defender. Chance missed.
