Both sides come into this clash on the back of losses and sit outside the top six so expect them to come out firing for three points in Perth

Perth were unlucky not to have at least salvaged a point against the Wanderers last start, sunk by a deflected Aaron Mooy goal just before the hour mark.
They have responded well to Alistair Edwards's coaching and at least are presenting a united and committed front.
They are unlikely to make the finals but they can make life uncomfortable for those hoping to get there.
Sydney fall into that category and will really drop off the top six push if they do not return east with at least a point.
Perth's overall record against the Sky Blues makes for dismal reading.
Sydney were dragged back into a top six logjam after falling to Melbourne Heart.
They have no elbow room, resting alongside the Heart on 27 points, two clear of the Roar but three behind fifth-placed Newcastle.
This has long been circled as a must-win match but they catch a different Perth side to the one going through the motions just a fortnight ago.
A few weeks ago you would have safely tipped Sydney, especially with so much riding on the result.
The Sky Blues still deserve favouritism but Glory are in party spoiling mode and are more than capable of stealing a point – or all three.
Perth will continue with the patient, slow build-up football that worked so well against the Mariners two weeks ago.
Sydney will not park the bus as they need maximum return from the journey west. A draw is the safest bet.
