Wolves take the lead at Ewood Park, as Dave Edwards seizes on a touch from Nouha Dicko to cut inside and crack a clinical low shot into the bottom corner.

Paul in Newcastle: Sanchez is better purely because of his commitment. Hazard sometimes look like he isn't bothered too much.

Luke in Portsmouth: Arsenal look unplayable. They often do. Problem is, it's not consistent. The day it does become consistent, is the day they have another Invincible season.

Mich in Leeds: How can home advantage make so much difference to teams? Stoke tore Arsenal apart at the Britannia a few weeks back but have been totally shambolic this afternoon.

Alexis Sanchez has moved to a more central position, with Mesut Ozil and Theo Walcott either side and the latter should have Arsenal's fourth when he has clear sight of goal after a swift break, but scuffs wide.

Goa...oh no. Stoke think they have clawed one back as Geoff Cameron volleys in, but does so from an offside position. Ironic cheers from the home fans and to make matters worse an announcement at the stadium informs Stoke fans that there is trouble with trains back to Staffordshire, "3-0 and you can't get home" chant the home fans. Harsh.

Abu Ali:, external Sanchez, Walcott and Ozil all on at the same time! Only took 6 months!!

Jay:, external There seems to be absolutely no purpose in Stoke's play - Arsenal have been that good!

Bojan has not been able to influence this game as much as Stoke would have liked and Mark Hughes makes his final change, replacing the former Barcelona man with Stephen Ireland.

Arsenal also make a change as Mesut Ozil returns after three months out with injury, coming on for Olivier Giroud and his first touch is met with huge applause from the home fans.

No score at Ewood in a match of very few chances. The hosts are having most of the ball and the better of the play but are yet to create and finish the chance which will reward their good build-up.

Alex Oxlade-Chamberlain has had a great game but Arsene Wenger decides his afternoon is done and he is replaced by Theo Walcott for the final 20 minutes.

BBC Radio

Former Stoke captain Andy Griffin on BBC Radio Stoke: "Stoke have played themselves into trouble a couple of times. They don't need to be too intricate - they should just play a diagonal ball onto Peter Crouch's chest."

Just as I type there is little flow to Arsenal's attack, they go and produce a fine attacking move as Alex Oxlade-Chamberlain puts Santi Cazorla through but his shot from a tight angle lands on the roof of the net. Arsenal are going for a fourth.

There is not quite the same flow to Arsenal's attacks in this half like there was in the first but pretty much every time they do get forward it is through Alexis Sanchez on the left. They can't handle him and he charges at the defence again before feeding the ball to Olivier Giroud, but his shot is deflected behind for a corner.

And another booking for Stoke, this time Peter Crouch is shown a yellow card after sliding in on Francis Coquelin. All getting a bit scrappy now.

Geoff Cameron is having a torrid afternoon trying to deal with Alexis Sanchez and frustration gets the better of him as he picks up a yellow card for pulling the Chilean's shirt.

Nathan Daniels:, external Am i the only one wondering which one footyographer thinks is a class above (see 51 mins) - #alligatoralltheway

Aidy Muttram:, external Anybody else notice Sanchez move the ball back a yard to give himself a better chance of scoring/getting more bend?

Finally an effort on goal from Stoke as they win a free-kick 25 yards out, but Marko Arnautovic sends it well wide. A very comfortable league debut for David Ospina. He has had next to nothing to do in the Arsenal goal.

Former Stoke captain Andy Griffin on BBC Radio Stoke: "It could be a long second half for Stoke because every time Arsenal get the ball they look dangerous."

Stoke have the look of a beaten side now as they look on course for yet another trip to Arsenal with nothing to show. Mark Hughes sits back in his chair, arms folded and scowling. His side have yet to offer any attacking threat in this half.
