When was the last great international competition? Erm, um, ah ... Euro 2000? When was the last great Champions League? It's happening right now; it's always happening right now. And this semi-final tie encapsulates why. Hardly anyone thought Liverpool could eliminate Manchester City and yet they did, dispensing a savage kicking in a ferocious atmosphere; and hardly anyone thought Roma could eliminate Barcelona and yet they did, dispensing a different kind of savage kicking in a different kind of ferocious atmosphere. As such, no one knows for certain what will happen in this semi-final tie, and yet everyone knows for absolute certain that whatever does happen, it will be unmissable. As human beings, it is our compulsion and it is our duty to wade right in.
