Sounds like it's been raining all night in Brisbane and forecast to rain most of the day. Playing condition could well be wet and heavy under foot.
Quote from a roar forum.
The weather will come in to team selection now. It’s been raining hard pretty much all night (I’m 6km’s from the stadium and it’s taken a soaking) and will rain pretty much all day and through the match.
Anyone remembering that Roar rain game where they had to stop because the the pitch was unplayable. We had the lead and Durante was furious arguing with the referee because he didn’t knew that would automatically turn into win for use because it was beyond the 60 min.
Update:
Burns dancing through the whole Brisbane defense, good times!
