The thousands of away fans that caused a delay to kick-off with their antics in the build-up to Arsenal vs FC Koln on Thursday did not have to wait long before they could celebrate their club's first goal in European competition for 25 years.
Arsene Wenger named an 'experimental' side with a big game against Chelsea coming up at the weekend, but things did not go to plan as the visitors took the lead in bizarre circumstances.
Goalkeeper David Ospina was caught out after a poor clearance and was immediately punished from long range by Koln striker Jhon Cordoba who caught the ball as sweetly as possible.
A terrific strike, but the keeper has to put his hand up for that one.
That roar is not something you would typically hear for an away goal, but if it wasn't painfully obvious already, this match matters a great deal to FC Koln and their fans, although UEFA will not be thrilled by what took place before kickoff.
