Well seeing as they play in the Eircom league Derry would be an Irish club, but seeing as Cliftonville play in N. Ireland they are considered a British club, just like Celtic are a British club, and if the flag controller wants to complain about Chelsea on a tricolour then Cliftonville or Celtic should get the same abuse, or is it just the English that get abused around here.
By the way Bratislava was ok in my book when I travelled there a few years back,nice eastern European city not quite the standards of some cities in the west but if you go to a developing eastern European country thats what you sort of expect. Some of the people here complaining about beers, taxis, nightclubs etc would want to take a trip back to the 70's or 80's in Dublin.
