Solid performance, though he had exceptionally little to do bar cutting out one cross in the first half. Made one good stop late on.
Benefited from the fact that West Brom only fielded a single striker, but was quick off the mark when needed and cleared the ball well. Went on a barnstorming run in the second half that almost led to a goal, and was appreciated by the fans.
A very impressive game for the right back, who put in numerous crosses from the right that caused panic in the Baggies' box. Caused real havoc down the right wing, and even outshone Theo Walcott in attack.
Was imperious in the air, and got on the score sheet for the first time in almost two years, though admittedly he has been injured for around half of that time. Should have doubled his tally for the season early in the second half. Made a great late block to deny Tchoyi.
A calm and assured performance from the Welsh captain, played the ball well and got out of tight situations with ease. Almost added a goal to a neat display, but dragged his shot just wide.
Wonderful pass to find Walcott in the build up to the first goal, the midfielder was classy in possession. Rounded off a good overall display with a nice finish to make it three.
The left back's defensive abilities have been questioned in recent weeks, though he had barely any of that to do today. Attacked well and found team mates with some neat passing.
Dominated the midfield, allowing Zoltan Gera no space at all. Was also decent with the ball, playing a key part in the second goal.
A disappointing performance from the winger considering the rest of his team was in such good form. He offered some decent running, but both his final ball and first touch weren't quite up to scratch and he was replaced late on.
A rather quiet performance from the attacker, but he did serve his purpose well, linking up to good effect with the midfield trio and getting into space well on the wing.
R. van Persie
Another goal for the Dutchman as well as assists to Vermaelen and Arteta. He is in the form of his life at the moment, and produced another good display today.
Not a great day for the goalkeeper, though there was little he could do about the goals. Stopped Walcott's shot well with his legs, only for Van Persie to tap home, and had no real chance with the other two goals.
Had a fairly decent game, but the away defense was under pressure from the off and it eventually told.
The right back didn't have much of a chance to attack, but was largely solid defensively, keeping Gervinho quiet for much of the match.
Was forced off early with a facial injury but recovered well and was the visiting side's best player.
Was turned inside out at one point by Jenkinson, and failed to prevent the right back having a good day at the office, though he was perhaps more occupied with stopping Walcott which he did well.
Found himself in space once in the match, but dragged his long range effort well wide. Screened well but the Arsenal midfield were completely dominant.
A largely anonymous performance from the midfielder as Arsenal kept him out of the game.
Missed one of the best chances for the visitors, and he knew it. His frustrations were clear for all to see as he berated a linesman late on.
Will be disappointed not to have made more of a mark at his old club considering last year's performance as he was forced to track back to cover Jenkinson.
Tried extremely hard and put in the yards but couldn't hold the ball up well enough as the Baggies kept losing possession.

Looked dangerous and combined well with Andre Santos almost immediately after being introduced.
Came on when the game was virtually won and did well on the ball, finding Van Persie who laid the ball off for Arteta's goal.
Came on late when the game was won, but didn't get too much of the ball as Arsenal seemed set to play keep-ball rather than really stretch in the closing stages.

Replaced Gera and immediately switched to the target man role. Missed arguably club's best chance as he shot at an already prone Vermaelen when through, but held up the ball well.
Came on with just under 10 minutes to go but couldn't get involved as Arsenal played keep-ball.
Came on with 20 minutes to go but rarely got involved in the match.
