I reckon we'll have an exisitng A-League player next week.
There, I've said it.

Existing? lol
I think HN uses "existing" in the sense of "still breathing" - which is important for any footballer.
"Not existing" would not be so good. Maybe for a fullback, but not a striker. 
I was referring to the fact that if he's an existing A-League player then he'd be contracted to a club... or is he 'contracted' to one of the expansion clubs that do/don't exist? lol
