There's a nervous start from the home side and the Hammers are looking the more dangerous of the two sides. Here Mark Noble glides away from Arsenal's Santi Cazorla Photograph: Paul Gilham/Getty Images

Arsenal finally threaten the West Ham goal after 14 minutes when Lukas Podolski finds room to whip in a cross but it's just too quick for Olivier Giroud, six yards out, to connect with Photograph: Glyn Kirk/AFP/Getty Images

Olivier Giroud, here holding off Pablo Armero, wastes a glorious chance to give Arsenal the lead when, after being put through by a great ball from Cazorla, he attempts a woeful dink over Adrian Photograph: Paul Gilham/Getty Images

Giroud's shocking effort might prove to be costly. Antonio Nocerino gets into the box down the right, Wojciech Szczesny saves his effort but the Italian is live to the free ball, poking it back into the six-yard box where Matt Jarvis arrives bravely to head in from off the high boot of an Arsenal defender Photograph: Tony O'Brien/Action Images

The Hammers' lead lasts just four minutes as the ball cames to Cazorla on the edge of the area, he drops a shoulder and plays a delightful reverse-pass through to Lukas Podolski. For a moment, he looked to have got the ball stuck under his feet but he sorted himself out and then hammered a low drive past Adrian.

Olivier Giroud makes up for his awful first half miss when he gives the Gunners the lead just before the hour mark. Vermaelen is around 45 yards out and takes a touch and then knocks a long high ball towards Giroud, who showes great strength to hold off Reid and Carroll, take the ball down and then ram a low finish through Adrian's legs from close range.

Olivier Giroud kissed the Arsenal badge on his shirt then pulled of the black armband the players are wearing in memory of the 96 Hillsborough victims, kissed it before looking to the heavens Photograph: Paul Gilham/Getty Images

Lukas Podolski evades James Tomkins and then also does so again in the 78th minute when he gets his second and Arsenal's third. Aaron Ramsey, from Giroud's pass, directs a preposterous header through to Podolski who holds off Tomkins before blasting the ball high past the helpless Adrian Photograph: Paul Gilham/Getty Images

An emphatic finish tops off an emphatic second half performance by the Gunners, whose keeper Szczesny hasn't had a save to make in the second half. Arsenal are back in the Champions League spot for the time being as Everton face Crystal Palace on Wednesday evening. Final score: Arsenal 3-1 West Ham United Photograph: Tony O'Brien/Action Images
