according to the FFA this is a "weekend of rivalries"

friday - coasties v nix (massive rivalry)
saturday - victory v reds (the original derby*)
saturday - perth v city (man, this rivarly is bigger than man c v man u)
sunday - sydney v wanderers (ok, i'll accept this is a genuine derby)

why the hell is the sydney derby on at 6:30pm on a sunday?

* but you know, not really a derby
