Melbourne Victory attacker Kosta Barbarouses lamented his team's sloppy mistakes after a 2-1 Derby loss to City.
Barbarouses set up Victory's equaliser, which came through Leroy George's first goal for the club, at Etihad Stadium on Saturday night.
That goal cancelled out Marcin Budzinski's opener for City, which claimed three points through a deflected Bruce Kamau effort.
While Barbarouses felt Victory deserved a point, he rued the errors made by his side.
"We probably weren't at our best, we've got to be honest," the New Zealand international told Fox Sports.
"I think we conceded two very sloppy goals where we could've done a lot of things better.
"We created a good goal and a few good opportunities, but at the end of the day those sloppy mistakes cost you and it cost us three points."
The loss was Victory's second straight to start the Hyundai A-League season after an own goal cost it in its opener against Sydney FC.
Barbarouses called for improvement from his team ahead of a trip to Adelaide United on Friday night.
"I think the boy (Kamau) who scored ran about 60-70 metres with the ball. We maybe have to get across and stop the play a little bit, but we're not going to point fingers at anyone," he said.
"Maybe our intensity as a whole wasn't good enough and that had a flow on effect. We need to be better."
