Because they don't want to pay.
and this is the major problem, last night we got beat and beat badly by one of the biggest names in football, if we wanted too we could bring a big aussie name into the squad and an international player too. Will we? No, why cos the owners know better than every other a-leahgue team out there. Terry couldn't afford a marquee, our owners can, but they seem to want the team to magic up some attractive football which is something we know they are not really capable of.
