Arsenal manager Arsene Wenger said his side lacked something during their 1-0 Europa League loss at Cologne on Thursday.
Despite losing, the Gunners still finished top of Group H after rivals BATE Borisov and Red Star Belgrade played out a 0-0 draw.
The Cologne goal came from a Sehrou Guirassy 62nd-minute penalty after the same player was adjudged to have been fouled by Mathieu Debuchy.
The Gunners second-string side had plenty of possession on the night, but could not find a way through, much to the disappointment of Wenger.
“We missed a little bit of accuracy in our passing in the final third that is required to score more goals. We had plenty of dangerous situations, but we always missed a little something to finish our chances.
“I must also say that Cologne defended with spirit, with commitment and overall the crowd was absolutely fantastic for them.
And in typical Wenger fashion, he said he disagreed with the spot-kick decision that cost Arsenal the game.
“We had a lot of possession. We lost the game to one shot, basically.
“It was a very nice penalty that we have to take on board. It was honestly not a penalty at all.
Fans, though were not impressed with the loss to a team that is rock bottom of the Bundesliga and have not won a league game all season.
So, Arsenal basically lost to Crystal Palace.

BATE and Red Star draw, handing Arsenal the group win. Which means we’ve sat through this dreadful game for no reason at all….
