In what began as a nice bit of organised street theatre, a portion of the fan-base travelling with FC Köln have turned rather more aggressive as the evening has progressed.
Seen here clashing with stewards inside Arsenal's Emirates Stadium, there are fears that the initially delayed kick-off may result in the eventual postponement of Arsenal's opening Europa League match.

The match has already been delayed for an hour due to the congestion of fans - many of whom arrived without tickets - around the Emirates.
Captured on video by Arsenal Fan Tv, this clip demonstrates the frustration that was beginning to spill over outside the ground.

Although it is impossible to ascertain the full extent of the problem, it has been announced that FC Köln's players have began warming-up and, as things stand, the match is due to begin at 9.05pm.
