Central Coast Mariners legend and now Edgeworth star Daniel McBreen has a history of facing off against the Jets at A-League level and now he is plotting their downfall from inside the club ahead of Wednesday's FFA Cup round of 16 match.
Now coach of the Newcastle Under-15 team, McBreen has infiltrated the opposition and will be hoping his reconnaissance from Jets HQ can be the secret weapon the Eagles need to cause a brilliant upset.
The 42-year-old striker joked he was given a frosty reception on Monday from Jets head coach Ernie Merrick who was determined to not let any club secrets fall into the wrong hands ahead of the unique Newcastle derby at the Eagles' home ground, Jack McLaughlin Oval.
"I walked into Ernie's office and asked him what he was working on and got told to get out of his office," McBreen said
"Obviously I have a foot in both camps so it has been really funny in the lead up to this match.
"There has been a bit of banter between myself and the Jets boys which has been great fun."
While it has all been fun and games between McBreen and his Newcastle Jets colleagues, the 2012/13 Joe Marston Medal winner admits the game is serious business for Edgeworth.
It is the second time the Eagles have reached the FFA Cup round of 16, after their 5-1 defeat at the hands of Western Sydney Wanderers in 2016, and they're determined to make history by defeating the big boys of football in Newcastle.
McBreen, who is battling to be fit for the match after tearing his calf in the warm-up of Edgeworth's FFA Cup round of 32 win, said it is set to be a special night for the club.
"We couldn't have wished for a better opponent for this match than our regions own A-League side in the Jets," he said.
"There is plenty of buzz and anticipation building for this match.
"I've been told as of Monday there has been 2500 hundred tickets sold for the game so it is going to be a very special atmosphere."
Boasting a side brimming with young talent, Edgeworth should be able to push the Jets all the way according to McBreen.
And while he admits the NPL side will be major underdogs for the clash, the A-League Championship winner thinks there could be a few chinks in Newcastle's armour which Edgeworth could take advantage of.
"Everyone will be expecting Newcastle to make light work of us but I think we have a team capable of causing a few headaches," McBreen said.
"The Jets have a few defenders out for this match so maybe that's our chance.
"We know it will be an uphill battle but this Edgeworth team won't go down without a fight and with our home crowd behind us anything could happen."
If Edgeworth were to pull off a miracle win, McBreen has already planned his celebration for when he returns to work with the Jets.
"I'll walk into the office like Connor McGregor," he joked
"There will definitely be some banter but obviously working for the Jets I think it will be best I just have a smile on my face and get to work before Ernie gets cranky with me.
"It's going to be a great night and no matter what the result is I suppose I come out a winner."
