Uefa inspector to look into crowd trouble during Arsenal's clash with Cologne
A Uefa inspector will seek answers from Arsenal and Cologne over the cause of the crowd trouble which marred last week's Europa League meeting between the sides at the Emirates Stadium.
European football's governing body said on Friday it had decided to appoint an ethics and disciplinary investigator in a bid to determine the circumstances surrounding the match on September 14.
The game was delayed by an hour as ticketless Cologne fans tried to gain entry to the stadium. The visitors were issued with 3,000 tickets, but around 20,000 Cologne fans were believed to have made the journey to London.
Five arrests were made over the course of the evening and Arsenal announced last Friday they were conducting a full review of the night's events.
Cologne face four disciplinary charges - crowd disturbances, setting off fireworks, throwing of objects and acts of damage - while the Gunners have been charged for blocked stairways in the away supporters' section.
UEFA also announced Everton had been fined 10,000 euros (£8,875) for objects being thrown during their home Europa League tie with Hajduk Split last month, and Russian club Spartak Moscow have been banned from selling tickets to their supporters for their next Champions League away game after a flare nearly struck a referee during their draw at Maribor last week.
