The difference is Real v Barca would have no trouble. Rags v dips would have thousands trying to jib in, thousands stealing tickets from their own fans, thousands fighting each other over some pretend rivalry. Waiters would be assaulted, locals pushed into fountains, the police would be assaulted by the permanently offended, I could go on but suffice to say it would make Rourkes Drift look like a Teddy bears picnic and the compo claims will keep solicitors in work for years because, don't forget, it will be Uefa/Garda/Government/City's fault.
