Sydney FC could spend at least two seasons playing at Leichhardt Oval as early as next year, should Allianz Stadium jump the queue in the state government's stadium plan.

This season could be the Sky Blues' last at Allianz Stadium in its current format with the venue set for an earlier-than-expected upgrade. That could begin as early as May next year as safety concerns over deteriorating facilities at Moore Park may prompt a fast-tracking of the state government-funded renovations for a likely 45,000-seated arena.

Should Allianz Stadium leapfrog ANZ Stadium at Olympic Park on the list of priorities on the $1.6billion stadium plan, Sydney FC have already begun preparing to relocating to Leichhardt Oval while construction takes place.

The club identified the inner west because it is one of the largest catchment regions for Sydney FC members. It is also on the doorstep of rivals Western Sydney Wanderers.
