I think people are reading too much into it all. (If I was a Hewitt fan, I'd think otherwise) If David says something like "They shouldn't bother coming, we will wipe the floor with them. No security can protect you from the might and power of Argentina!" *followed by an evil laugh* then it's a different story.
Who do we have? Potentially Arthurs, Luczak, Guccione... maybe Mr Perfect if he feels up to it and doesn't injure himself or put his family first
Maybe Xristos can play for us. Anyone willing to pay for a one-way airfare?
