Celtic are the only group of supporters known to man that have more Gingers than Leeds have, so on that basis it'll never happen.
If this match ever happens, would make your matches against WHU look like a "kiddies tea party!" How about playing Pompey? Used to be good when you visited Fratton??
That'll get you killed in S E London. (also any pub you walk into, eating a kebab, sitting on grass, wearing a watch, talking on a mobile.......)
