Sixteen minutes in and on the edge of the Arsenal area Aaron Ramsey takes too many touches and is set upon by Marco Reus, the ball eventually breaking to Robert Lewandowski. He touches it to the right for Henrik Mkhitaryan, who throws Koscielny and then strokes a lovely finish into the bottom-left corner with his right foot Photograph: Tom Jenkins

With half time approaching, Arsenal get back in the game courtesy of a some hesitant goalkeeping from Roman Weidenfeller, who never quite convinces. Sagna curls a cross into the box from the right, where Giroud, Subotic and Weidenfeller, who waiting. Weidenfeller isn't determined enough, though, and the ball takes a slight deflection off the sliding Subotic ... Photograph: Tom Jenkins

And the ball is divert past Weidenfeller and sitting up for Giroud to smack into the empty net from all of two yards out. What a stroke of luck for Arsenal, who find themselves level without playing especially well yet. Half-time score: Arsenal 1-1 Borussia Dortmund Photograph: Tom Jenkins

No way through for Giroud this time Photograph: Tom Jenkins

He's having the same trouble in the air as Mats Hummels beats him to the ball this time Photograph: Tom Jenkins

With eight minutes to go Dortmund hit Arsenal on the break. Grosskreutz speeds away down the right flank, leaving Gibbs in his wake and then sends a cross to the far post where Lewandowski, totally unmarked with Sagna dragged inside, slams a low volley past Szczesny.

The manager isn't too happy too, especially as it's his 64th birthday today, so not the birthday present he would have been hoping for Photograph: Tom Jenkins

The final whistle goes, bringing joy for Borussia Dortmund and despair for Arsenal. With Napoli beating Marsailles to join Arsenal and Dortmund on six points it's pretty tight in the group now Photograph: Tom Jenkins

The Borussia Dortmund players and fans endulge in a spot of mutual applause. Final score: Arsenal 1-2 Borussia Dortmund Photograph: Tom Jenkins
