Arsenal's unbeaten Europa League run came to an end in Cologne - but they are still through as group winners.

The Gunners had won their first four but were outdone by a controversial penalty.

Sehrou Guirassy went down under Mathieu Debuchy’s challenge and Russian referee Vladislav Bezborodov gave a penalty which looked very harsh.

Guirassy dusted himself down and beat David Ospina from the spot.

Arsenal

Ospina 6 - Barely in the game and could do nothing about Cologne penalty.

Debuchy 8 MOTM - Combative throughout. Harshly penalised for penalty on rare opportunity to impress.

Mertesacker 7 - Gunners skipper rarely troubled on Europa League outing

Holding 6 - Little to do but like so many others, will hope to be back in first XI plans.

Chambers 6- Given a rare opportunity at wing-back but looked to come inside at every opportunity

Maitland-Niles 7 - Bright down Arsenal's left in Germany

Coquelin 6 - Came close to scoring during first-half

Elneny6 - Doesn't affect the game enough going forward and needed to do so here.

Wilshere 6 - A few nice touches but not at the level he has been in this competition

Giroud6 - Not really in the game. Surely he can't be happy with just Europa League action.

Welbeck 5 - Given some much-needed minutes but took off at half-time.
