The SCG Trust has ruled out moving a Super Rugby clash scheduled for the night before a potential A-League grand final as doubts about the state of the Allianz Stadium surface increase.

The grand final is not for another two months but already serious concerns exist about the state of the pitch at the venue most likely to host the A-League's biggest game.

Such is Sydney FC's dominance this season that the Sky Blues are already planning for the big day. Football Federation Australia governs the bookings, venues and dates for finals, but it is understood the Sky Blues will fight tooth and nail to keep any home finals at their spiritual home in Moore Park, rather than move to ANZ Stadium at Olympic Park.

However, that could come at a major cost to the quality of football during the finals with those potential fixtures falling between a heavy schedule of rugby league and rugby union games at the venue.
