Melbourne Victory boss Jeff Hopkins lamented his team's display in its 3-1 Westfield W-League loss to the Newcastle Jets on Friday.
Victory needed a win to boost their finals hopes but were beaten by a clinical Jets outfit.
Teenager Kyra Cooney-Cross scored her first goal in the Westfield W-League to equalise after Tori Huster's opener before Hannah Brewer and a Katie Stengel penalty saw the Jets to their win at AAMI Park.
"Some games when your season is almost on the line and we really needed three points to keep us in touch," Hopkins said.
"Maybe we built it up a little bit too much for the players because we didn't really do ourselves justice.
"Myself, the whole of the team, the whole of the squad are disappointed with the effort we put in, especially here, when you get an opportunity to play out on AAMI Park in front of your home supporters.
"We didn't do ourselves justice."
The loss was a blow to Victory's chances of reaching the finals, left six points adrift of fourth-placed Perth Glory, although they do have a game in hand.
Hopkins said his team would not give up in its push for a top-four finish.
"Every game is now a cup final for us, we've got some tough games over the next couple of weeks," he said.
"We've by no means given up but we've made it difficult for ourselves."
