Cologne get another free-kick in their own half and pump it straight to Ospina who returns with a kick of his own. Mere pumps it back downfield, and as Nketiah passes back once more, the clock ticks over and the referee blows for full-time!
90' +3
It's another great save from Horn too - Wilshire swings it in close to the goal mouth, aiming for Iwoba at the far post and the keeper rises brilliantly to pick up.
90' +2
Close for Wilshire! Lehmann makes a weak effort to clear from the box and he gives it cheaply to the Gunners man 20 yards out on the right - whose shot is tipped over the top by Horn. Corner.
90' +1
A free-kick to Cologne in their own half now as Iwoba clips Sorensen whilst challenging for the same ball.
90'
Four added minutes on the way in Germany. Can Arsenal snatch something for their effort?
89'
Two great saves from Timo Horn! The first comes off a Nelson toe-poke of a shot, from only five yards away as the youngster cuts into the box - and then a second from a close-range Wilshire effort after the ball is swung back in seconds later from the wing.
88'
S. Guirassy gets yellow.
A late booking for Guirassy now after a clumsy tackle in midfield.

84'
E. Nketiah enters the game and replaces M. Debuchy.
A final change for Arsenal now as Debuchy is replaced by Nketiah.
83'
Appeals for a handball down the other end now as Olkowski claims his attempted cross into the Arsenal box was knocked down by the hand of Mertesacker - the referee waves play on instead.
Minute
Description
82'
An almost identical pass again from iwobi, seeking Wilshire - and this time, the ball skips across the face of goal and to the feet of Mere.
80'
Iwobi pushes forward down the wing and tries to swing a ball across into the box from the left for Wilshire; Ozcan doubles back and deals with the danger.
78'
Wilshire steos uo for the corner this time and swings it in to Mertesacker in the middle of a crowded box; Rausch gets his head there first and pushes it back into midfield.
77'
Close for Giroud! He comes onto a lovely Wilshire pass and canters into the box - and is caught in a sandwich between Timo and Jennes Horn. Corner to Arsenal, but there is a pause for treatment to Jannes Horn who is prone on the floor.
75'
A corner now for Arsenal which El Neny takes, but it's a poorly placed kick and Rausch has no trouble cleaning up.
73'
M. Lehmann enters the game and replaces Y. Osako.
Osako is the last change for the hosts - with Lehmann on in his place.
Debuchy puts a masterful cross into the box for Giroud and only some neat placement by Mere manages to deny the striker from landing a touch dead in front of goal.
72'
Guirassy picks up an intercept and whips off down the left wing again, only stopped by some nifty tackling from Nelson.
70'
Some other stats to chew on; Cologne have only had four shots all night, Arsenal have had 12. That alone shows how unfortunate Arsenal are to be behind - but they need to push forward with more pace.
68'
Cologne get the ball back into Arsenal's half for the first time since that penalty goal and swiftly lose it again. With only 33 percent possession, they will be absolutely over the moon to have the lead.
67'
R. Nelson enters the game and replaces C. Chambers.
That is the last act for Chambers in this game though - he takes his place on the bench, replaced by Reiss Nelson.
It's another fabulous cross from Chambers, drifting it in for Wilshire - and the striker's header just floats over the crossbar.
66'
A neat solo effort from Wilshires, who picks out a run around two defenders and launches a crack from dead in front of the eighteen yard area for goal, forcing Horn to deflect it out for a corner.
64'
Arsenal try to spring back quickly as Chambers lifts a wonderful cross into the box that Klunter puts out for a corner before Giroud can get there. El Neny turns it in towards Iwobi - and Horn gets the punch to clear.
62'
Penalty goal scored by S. Guirassy for FC Cologne!
Goal to the hosts! Guirassy sticks it straight down the middle with a little lift and sends Ospina to his right. Suddenly, Cologne find themselves in the lead of a game they looked only half-invested in.
61'
Penalty to Cologne! Guirassy slips a ball into the box and follows it through, before clashing with the side of Debuchy and going to ground. The referee points to the spot - and it is Guirassy who will take.
60'
A chance for the hosts as Jojic picks up a loose pass from Holding at the back and feeds it through to Guirassy - only for the forward's finish to be the tamest of efforts, dribbling towards Ospina.
58'
It takes a bounce off the wall and goes out for a corner, which El Neny plays short - and Arsenal then loose possession with Sorenson darting across to collect.
57'
Maitland-Niles earns a free-kick on the sharp-left side of the Cologne box now after Klunter pulls him off the ball. El Neny to take...

M. Debuchy gets yellow.
48'
A yellow for Debuchy now as he comes in with a silly, careless lunge on Guirassy.
46'
A. Iwobi enters the game and replaces D. Welbeck.
And we're back underway in Germany. Welbeck is off with Iwobi on - can he give the Gunners that extra boom upfront to break the deadlock?
45' +2
Ozcan gets it in midfield and tries to push wide to Klunter - only for the referee to blow for half time before they can make something of it.
45'
El Neny launches a long-range shot from 35 yards out in front, only for it to sail well over. Two added minutes incoming.
43'
Wilshire tries to cross into the box from Welbeck but Horn is alert to the danger and deals with it with a neat punch.
41'
It's been a promising first half from Arsenal, as Maitland-Niles sees an attempted shot take a rebound off Klunter. For a team filled with less first-choice names, the Gunners are convincingly out-performing Cologne.
39'
A early change for the hosts now as Maroh appears to have tweaked his hamstring. Hobbling badly, he is helped from the field and Konstantin Raush takes his place.
38'
K. Rausch enters the game and replaces D. Maroh.
Free-kick to Arsenal now , 30 yards out on the left after a pull on Maitland-Niles. El Neny curls it in, looking for Wilshire, only for the forward's header to spear it back out into midfield the wrong way.
37'
Jojic breaks free down the wing on the right for Cologne, only for his attempted cross to Osako to fall to Holding.

33'
Maitland-Niles - who is putting himself all over the place tonight - cuts back on himself on the left wing and into the edge of the box, before spraying a shot for the far post wide by a couple of feet.
31'
Off the post! Coquelin runs onto a great Welbeck flat pass into the box and controls it nicely; his finish rattles the woodwork and rebounds the wrong way around, going out for a goal kick.
30'
Maitland-Niles wrongfoots Sorenson at the back and lobs a cross from the left of the box to the right; Chambers can't connect and takes the sting out of his shot with a bumbled effort straight to Horn in goal.
28'
Osako gets a neat pass twenty-five yards out on the left and looks to pull a shot into the bottom right corner; only, he slips on the lush turf and sends it wide.
26'
Klunter makes a break down the right with a nippy run; Maitland-Niles sweeps in to jockey for and then control the ball, delivering it safely to a crouching Ospina.
25'
The Gunners man, who has had terrible luck with injuries, is thankfully OK and Arsenal pump the free-kick downfield.
24'
It's an entirely makeshift eleven tonight from Arsenal - with six who previously played against Cologne. Debuchy is back in the side tonight - and there's a moment of concern as he takes a heavy tackle and goes down.
22'
Close for Wilshire after he gets a cross in from Welbeck on the left, only to guide it straight to Horn.
20'

Offside against Maitland-Niles on the left wing after he takes a pass via Giroud - though replays cast some doubt over the linesman's decision.
15'
El Neny tries to thread a cross out wide on the right to Chambers, only to put too much weight on the effort and it runs dead before the youngster can get there.

6'
What a shot from Cordoba! The Cologne striker rips down the right wing, canters into the box and launches a wonderful strike towards the top left corner, forcing Ospina to leap. Holding completely missing in defence there - corner to the hosts.
4'
It has been a terrible domestic season for Cologne this year, after the highs of European qualification previously. They have scored four goals in twelve league games - and sit rock bottom of the Bundesiga.
2'
Arsenal whip it in through El Neny, and keeper Timo Horn reads it well to collect and clear up.
1'
And we're underway in Germany! The Gunners are playing left to right - and go close early on, as a neat Wilshire pass is tapped on to the left by Welbeck to Maitland-Niles, who sees his effort deflected out for a corner.
The Gunners have won just four of their 17 away games vs German opponents in all European competition with all of those victories coming against different sides Werder Bremen, Hamburg, Bayern Munich and Borussia Dortmund. Against Cologne however, they are yet to win on the road.
Victory here would mean the Gunners become the first English team to win away at five different German opponents in all European competition as a result. Cologne however have lost just two of their last 20 home games in the UEFA Cup/Europa League, though these defeats have come in their last five games.
The Gunners have scored in each of their last 13 away games in European competition, last failing to find the net in September 2014 in a 0-2 defeat to Borussia Dortmund. Olivier Giroud – who starts - has made more touches in the opposition box in the Europa League this season than anyone else, with 35.
The teams are out and we're moments away. Cologne are in all red; Arsenal are in blue and white.
Hello, and welcome to the penultimate matchday of the 2017/18 UEFA Europa League group stages, as Cologne host Arsenal in Group H. The Gunners are already through to the knockout stages, with ten points from four games, whilst their hosts sit bottom the table - but a win for the Billy Goats tonight could see them potenially join their opposition in progressing. Can they pull it off? Kick off is just around the corner.
It's been mostly one-way traffic for the visitors as a makeshift Gunners side have strolled around the park against a Billy Goats outfit low on self-belief. However, despite their best efforts, Arsene Wenger's men have been unable to find that goal to open things up. All square at the break; at half-time, it's Cologne 0-0 Arsenal.
It's a famous win for Cologne against a Gunners side who absolutely dominated the game across the park - with a Guirassy penalty doing just enough to give them three points and keep their hopes of progression alive. Arsene Wenger will be left to rue the many chances missed - 16 shots, in total - but his side couldn't find the snap that would help them get past an excellent Timo Horn at the back. Full-time in Germany, it finishes Cologne 1-0 Arsenal.
Well, that has blown the race to join Arsenal in progression from Group H wide open. The Gunners are through at the top, safe and sound on 10 points - whilst Cologne are now level in joint-second with Red Star Belgrade on six. The Billy Goats must travel to Serbia next time out - and now know that a European campaign in the new year rests in their own hands. Until then however, thank you for joining - and have a good night!
