Newcastle Jets will be facing a crisis if they do not get a positive result this Sunday. Following last night's toothless 3-0 loss to Wellington Phoenix, the Jets are now confined to the bottom of the A-League table with the worst goal difference in the competition.

This Sunday's home fixture against the North Queensland Fury could prove to be the most important match of the Jets' season, a loss spelling disaster whilst a win or draw would have them still in the hunt for a top-six finish.

Newcastle coach Branko Culina is aware that this is the case and is looking for a much-improved showing despite taking on the Fury on a quick back-up.

"Overall it was disappointing. We didn't take our chances and again we dropped our heads and that's a real concern," said Culina of the loss last night.

"We thought we saw some light at the end of the tunnel in the last couple of games against the Central Coast and Brisbane away from home.

"Our record away from home has been pretty ordinary. It's something we need to turn around and make sure we improve if we want to be challenging for better than where we are at the moment.

"Sometimes when you lose like we did, badly, it's probably good that you have a short turnaround because you're itching to get back into it," he added.

"We've got to travel back. It's a critical game and we're playing against a team we should beat at home."

The Jets host the Fury at EnergyAustralia Stadium this Sunday - kick-off is at 5:00pm.
