In dramatic circumstances, Glory had taken a 3-2 lead through Nikita Rukavytsya's powerful strike in the 81st minute, only to see an elusive win disappear when Jets skipper Jade North struck in the fifth minute of added time, slotting the equaliser after a lapse in concentration from Perth's defence.

Mitchell said he had no issue with the goal but was disappointed the game had gone for so long, saying he didn't know where four minutes of added time had come from in the first place.

He said: "Gutted you know ... where did that four minutes come from and then they extended it, felt like six minutes at the end.

"Where that came from, I don't know, (but we're) bitterly disappointed.

"From that point of view, it feels like a loss but we picked up a point and it should have been three, no denying that fact and I think Newcastle will find themselves very lucky today."

The Glory coach was also concerned with Newcastle's opening goal after Zetter pointed to the spot in the 19th minute when Perth's Dino Djulbic tackled Jets striker Joel Griffiths on the edge of the box, with replays indicating contact occurred outside the area.

Mitchell said: "Well, it was outside the box, I think everyone saw that who was there.

"I think every time we get this referee we just get a bit of bad luck you know, so that's unfortunate."

But he refused to comment on whether Zetter had officiated poorly in past matches involving the club.

"Well, I wasn't in charge then, but since I've been in charge, anyway, I won't say, I won't get myself into trouble. I can't afford a fine. We're not allowed to say anything," he said.

Mitchell, however, felt the overall performance - which included a goal of the year contender from Eugene Dadi - demonstrated the club's attacking potential after three seasons of below-average performances.

"Last year, it was all playing catch up and that's why it was important for us today for the club and for the supporters, that we won today, to get off the bottom of the table, get away from the bottom of the table scenario," Mitchell said.

"And, I think we were certainly robbed today and that's what's so disappointing."

"(But) we've got to pick ourselves up. The season's yet young and we've got to give out a big fight and a big challenge for that top four spot where the club wants to be."
