The Jets remained scoreless this W-League season after losing their round-two match against Perth Glory 1-0 at Members Equity Stadium on Saturday.

For the second week in succession the Jets had more shots on goal than their opponents, and on Saturday Newcastle enjoyed 66 per cent of possession.

"What we want from the midfield or front three is to score goals. We've played two games and we haven't scored, so obviously there's some people there who've missed out," O'Sullivan said.

"So we've got to see how we can fine tune that and make some changes."

Perth's Matildas striker Lisa De Vanna made her return to the W-League after a stint with USA side Washington Freedom and quickly found space on the counter attack in the ninth minute.

De Vanna released striker Elisa Dovidio whose shot was blocked by Jets goalkeeper Alison Logue.

But Logue could not stop Matildas midfielder Collette McCallum from curling in a left-foot corner into the back of the net.

De Vanna troubled Jets central defender Stacey Day throughout the half with her speed, but a collision with Jets skipper Hayley Crawford in the 35th minute slowed her momentum.

Late in the first half the Jets began to find space out wide through Gema Simon and Caitlyn Jarvie, but the execution in the final third remained poor.

The Jets dominated in the second half and pushed forward late in the game, but the front three of Jarvie, Leia Smith and Kate Hensman were unable to break down the Glory defence.

O'Sullivan said his young side was improving fast but was still getting accustomed to the 4-3-3 formation.

"I thought we looked a lot more threatening, it's just getting that ball in the net," he said.

"Once one goes in, more will follow.

"I think it's a little bit new because we've gone three at the top and the girls have previously been playing two at the top, so it's an educational thing as well."
