Celtic fans have been praised by the authorities for their behaviour as thousands of supporters travelled down to watch Tuesday night's 3-0 Champions League defeat at Manchester United. The Manchester authorities were desperate to avoid a repeat of the ugly scenes which marred the most recent visit by Rangers to the city.
Match commander Superintendent John Graves was delighted with the outcome.
He said on Celtic's official website: "Whilst I know the result of the game wasn't what Celtic fans would have wanted, the result of the overall event surely was.
"Making such events a success is not just down to the police and the clubs, it's a responsibility of everyone involved, especially the supporters.
"As the police match commander at Old Trafford, I would like to pass on my thanks to those Celtic fans who came to support their club in the finest traditions of genuine football fans, and ambassadors of Glasgow.
"From a policing and safety perspective, the game was a great success. There were very few incidents and arrests, and nothing that should detract from a great footballing occasion.
"I have to say that Celtic Football Club has every right to be proud of its fans. Those who braved the night in a windy and wet Manchester were a credit to the club.
"I would also like to compliment the Celtic stewards who helped tremendously throughout the game and added great value to the safety operation.
"We have a cliche in Manchester about the eyes of Europe being upon Old Trafford during these massive football games, and this was no exception.
"I believe that Celtic fans did a great deal to enhance not only the club's reputation across Europe, but also their own - well done."
