Newcastle have an assassination mission booked in for Friday - and their moving target is Aaron Mooy.
The Jets have been watching closely the Socceroo's exploits at his A-League home of Melbourne City, and know their fate at AAMI Park will largely ride on how well they can shut down one of the competition's most creative players.
"We've got to get his head down straight away so that he doesn't have all the time in the world on the ball," said defender Daniel Mullen.
"When he's got time on the ball he's effective, but if we can put his head down and put pressure on him we can still turn the ball over when he has it.
"It's more about doing the same (as usual) - keep it compact and get numbers around the ball and making it hard for him to play."
Mooy continued his brilliant form in City's midfield during Sunday's 3-1 thrashing of Central Coast, and had a hand in his side's opener when he curled a cross for Patrick Kisnorbo to head beyond Mariners keeper Paul Izzo's grasp.
Uruguayan striker Bruno Fornaroli, another of Mullen's cited threats - fired a second-half brace.
The Jets have defended valiantly under siege this season, outlasting champions Melbourne Victory and Wellington Phoenix, and coming excruciatingly close to a draw with Sydney FC.
But Mullen said extra caution will be required against Mooy to ensure no free-kicks are given away in the danger zone of the box.
"You could see in (Sunday's) game he took a couple where you thought `there's not way he's going to shoot', and he did. It took a good save from the goalkeeper to keep him out," Mullen said.
"He's put one on the head of Kisnorbo as well for the goal, so we're going to have to make sure we don't give away too many silly fouls in and around the box.
"Every game he's been instrumental. But at the same time they've got a lot of quality everywhere else on the park, so we can't just focus on one player."
