Despite going down to ten-men Melbourne City hung onto a 2-nil lead in Sydney thanks to heroics from goalkeeper Eugene Galekovic.
This was while Western Sydney Wanderers woes continue, with the clubs active supporters - the RBB - walking out at half-time in protest.
The match began a snoozefest. A cagey affair with both sides refusing to unleash their attacking speed and prowess as the Wanderers looked relatively stable in defence.
A long throw-in however unlocked their tight-knit line as Lachy Wales powered through a lackadaisical Wanderers back line and slotted home for 1-0. Only two minutes later Raul Llorente's poor defensive work allowed Riley McGree to set up Ritchie De Laet for a second.
Rostyn Griffiths was given his marching orders in the 55th minute while Eugene Galekovic kept the result intact for City. Two stunning saves in quick succession including a brilliant penalty save ensured Melbourne City lengthened their unbeaten run to three matches.
WESTERN SYDNEY WANDERERS
Vedran Janjetovic - 6
Janjetovic was late to charge out of his box for Wales' goal while De Laet's strike was hard to stop.
Tarek Elrich - 5
The birthday boy was caught out of position early in the second half, luckily the offside flag bailed out the right back. Elrich fell asleep as a long throw opened up the Wanderers defence as Wales stole the lead.
Patrick Ziegler - 5
Ziegler struggled to make his passes stick and struggled in communication with the midfield players, especially his German counterpart Alex Baumjohann.
Brendan Hamill - 4
Hamill defended well himself but struggled to organise his troops at the back with some horrific positioning leading to City's goals and countless chances.
Raul Llorente - 3
The whole Wanderers defence fell asleep as Wales pounced in behind and a throw in unlocked the doors for 1-0 at ANZ, Llorente could do nothing but chase.
His defensive frailty was shown only two minutes later after he was skinned by McGree who set up De Laet for number two.
