Several people were treated for minor injuries at Koln hospital. No-one has been charged follwing the offences.
All were interviewed and photographed before being escorted in police buses to trains heading for Belgian ferry ports.
A total of 128 people were arrested, 123 of which were English, their details are being passed onto anti-hooligan police in the UK.
The centre of Koln was full of revellers celebrating their May Dance festival. They fled when United fans ran in groups through the narrow alleyways and squares.
"Most of the action took place near the bars and especially around the Irish Pubs where the British had gathered," saidPolice Commissioner Helmut Langewald.
"It began as verbal abuse but escalated into physical violence shortly after. It took about an hour to regain control.
"The decision was taken to get them out of Cologne as quickly as possible. They were carted in convoys of police buses to the train station and put on trains to Belgium en-route to the Channel Tunnel or ferry ports."
According to a police spokesman the job was made easier as they had experience of dealing with Liverpool hooligans, who clashed with Leverkusen's after their quarter-final loss to Bayer.
Last night trouble however, was"much bigger" than when Liverpool were in town.
