About 150,000 Rangers fans were in the city when the violence broken out
A Rangers fan has admitted assaulting a police officer during rioting which broke out in Manchester after the 2008 Uefa Cup Final.
Mark Stoddart, 25, of Glasgow, pleaded guilty to assault and causing actual bodily harm at Manchester Crown Court.
Another man Scott McSeveney, 21, of Shotts, North Lanarkshire, denied the same charges on Friday.
Seven other other men pleaded guilty to violent disorder, while a further two denied the charge.
A total of 11 men appeared before the court to face charges connected to the violence that erupted in May 2008.
Mr McSeveney will go on trial at Manchester Crown Court on 15 March.
Greg McKenna, 22 of East Kilbride, Lanarkshire and Brian McVicar, 19, of East Kilbride, both denied violent disorder and will go on trial on 17 May.
Those who pleaded guilty were Gordon Forrest, 35, of Bearsden, Glasgow; James Bell, 42, of Cumbernauld, Glasgow; Thomas Murphy, 27, of Greenock; David McCullough, 20, of Burnage, Manchester; David Annette, 34, of Chorley, Lancashire; John Saunders, 31, of Cumbernauld; Michael Hindle, 21, of Leyland, Lancashire.
They will be sentenced at the conclusion of the trial in May.
About 150,000 Rangers fans travelled to the city for the Glasgow club's match with Zenit St Petersburg, which the Russian side won 2-0 in May 2008.
A big screen erected for fans without a ticket broke down, which led to disturbances throughout the city centre.
Rangers fans were involved in five hours of clashes with officers.
