Sydney United 58's grueling schedule finally caught up with them losing 7-1 to the Western Sydney Wanderers in the FFA Cup round of 16 on Wednesday night.
The Reds, who played 330 minutes of football last week, are in the stretch of five games in 14 days which culminates in the NPL NSW grand final against APIA Leichhardt Tigers on Saturday at Bankwest Stadium.
Miro Vlastelica's team held pace with their A-League counterparts in the opening 15 minutes with their trademark up-tempo style a feature.
But once Bruce Kamau found the back of the net from a cross the red and blacks took control. Goals to Kwame Yeboah and Daniel Georgievski made it 3-0 at the break.
Patrick Antelmi won and converted a penalty to give the travelling Edensor Park faithful at Campbelltown Stadium some hope they could replicate their come-from-behind win against premiers Wollongong Wolves from Saturday.
But it was short lived. A Matthew Bilic own goal and a red card to Yianni Perkatis saw the Wanderers resume complete control of the game and they added a further three goals including a screamer from Radoslaw Majewski. It was the club's highest scoring match in history.
The Wanderers will now face Melbourne City in the FFA Cup quarter finals, while the Reds will turn their attention to the NPL title which has alluded them since 2006.
