86' Koln are attempting to salvage something from this game, but in their over-eagerness to do so, Cordoba finds himself offside. Arsenal are in control at the moment, and it is reflected in their play, which is much more confident.
82' Kolasinac sends in a low cross that is cleverly dummied by Wilshere, with Walcott's shot blocked and then falling perfectly for Bellerin to slam home.

74' So close! Giroud with a lovely lay off finds Walcott in the box, but his cross is cleared out by Koln. The move ends with Alexis getting fouled and he is immediately back up to take the set piece. His shot is on target, but Horn makes a comfortable save.
72' SAVE! Cordoba gets the better of Monreal and then runs past Mertesacker into the box, before unleashing a low drive to the near post, but Ospina gets down well to make a smart save. A real warning for Arsenal!

44' Arsenal have had much of the ball here, but are struggling to make much of it, with Sanchez being forced to drop deep. Wenger has a real headache on his hands.

30' LUCKY! Rausch sends in a brilliant ball from the left, which Zoller is inches away from turning in, but Ospina manages to get ahead before fumbling the ball into Hector's path, and then clearing him out. Thankfully for Arsenal, the ref had blown for Zoller being offside beforehand.
28' Groans ring out at the Emirates as Elneny opts to pass the ball back instead of forward from a promising position. Koln win the ball back and burst forward on the counter, forcing a corner.
25' Alexis finds Giroud in the box with an early cross from the left, but a heavy touch results in a goal kick for Koln. Rather pedestrian stuff from Arsenal so far, with Koln holding on to their lead rather well, and looking dangerous on the counter-attack.
23' CHANCE! Holding does brilliantly to intercept the ball, playing it to Iwobi, who lofts it to Walcott running clear on the right side of the box, but the Englishman skews his shot wide while falling over under pressure.
20' There we go! Bellerin sends in a peach of a cross with Giroud rising high to head the ball downwards but cannot get enough purchase on his effort, with Horn collecting the ball.

8' In stark contrast to the scenes in the crowd, the game has been pretty uneventful so far, with Holding, Mertesacker and Monreal having plenty of the ball. There is the odd long ball forward from both sides, but the keepers have been first to it everytime.
