As such I don't think Leichhardt Oval is what Wests Tigers fans are clamouring for per se.
Additionally, plenty of current and past administrators at the Wests Tigers have admitted that playing games at Leichhardt Oval severely erodes its revenue base as corporates will not pay corporate rates due to the poor amenities at that ground.
