Coach Carl Veart says he's satisfied his Adelaide United side claimed a share of the points with Western Sydney Wanderers thanks to their 1-1 A-League draw, but felt the Reds might actually have pinched the win.

United were forced to play with 10 men for more than a half on Saturday, after Louis D'Arrigo was given his marching orders just before the break for a second bookable offence.

The Reds had opened the scoring on 10 minutes through Tomi Juric, who returned to the starting line-up following an injury, and looked fairly comfortable up until that point.

But holding on for the win seemed an unlikely prospect with the team a man down for the entire second half.

"At halftime, if you said to me we'll give you a point I would've taken it," Veart said.

"Most definitely when you play with 10 men for that long."

Still, Veart believed they could win.

"Yes, we're disappointed we didn't get the three points."

Despite the numerical disadvantage, United came out firing in the second half and enjoyed a solid 15-minute spell.

Adelaide should have added a second when Ryan Strain rounded Western Sydney shot stopper Daniel Margush but his shot from a tight angle rolled across the goal line with the empty net beckoning.

Veart said he encouraged his side to launch an attack on the Wanderers following the interval and it almost paid off.

"Yeah, we wanted to push," he said.

"A lot of the times when teams go down to 10 men they defend, defend, defend and you just can't get any relief.

"I didn't want that to happen. I wanted us still to attack and I didn't want us to drop too deep. And the boys, to their credit, did that."

The Wanderers weathered the storm and eventually equalised through substitute Simon Cox before having Mark Natta sent off in the final quarter hour after he held back Stefan Mauk who was through on goal.

Bernie Ibini, who set up Cox for the equaliser, should have snatched the win for the visitors but blazed high with the last kick of the game.

Western Sydney coach Carl Robinson remained positive and backed his players despite seeing them squandering that late opportunity.

"I'll stick with Bernie, I'll stick with that group in there," he said.

"Because my goalkeeper made mistakes today, my centre back made a mistake by getting sent off, my centre forwards made mistakes by not holding the ball up, my centre forward missed a chance, he made a mistake.

"So, we're all in it together."
