mindless thugs

Manchester police and the Football Association have urged fans of both Manchester teams to show restraint ahead of tonight's final leg in the Carling Cup semi-final.

Sir Alex Ferguson and Roberto Mancini have been told to remind their players of their social responsibilities as the two clubs face each other at Old Trafford. The first leg was blighted by incidents on and off the pitch, with the arrest of 18 Manchester United and Manchester City supporters.
