Arsenal and Cologne have both been charged by UEFA after crowd trouble caused their Europa League kick-off to be delayed by 60 minutes.

Arsenal have been hit with one charge in relation to blocked stairways in the away end while the Germans have been charged with four offences including acts of damage and throwing objects.

At times, the game seemed in real danger of being postponed, however it was decided that going ahead with the game was preferable to trying to disperse fans.

Arsene Wenger has called for an inquiry into the events, which saw thousands of Cologne fans gain access to the home areas.

While there were reports of some scuffles inside the ground, and disturbances outside, only five people were arrested by police.

Earlier today, Arsenal issued a statement about the events. The have launched a review, adding, “The 3,000 tickets issued to Cologne fans was in line with competition rules but it is clear many more visiting fans arrived, causing significant congestion and disturbance outside the stadium before kick-off. Many tickets were sold through touts and this is very disappointing.”
