Newcastle coach Gary van Egmond called on the club's management to re-sign Mark Bridge after the striker fired the Jets to their first A-League championship.

Bridge scored a fine goal in the 64th minute to give the Jets a 1-0 win over minor premiers Central Coast in the grand final at the Sydney Football Stadium.

Olyroos striker Bridge, who is off contract, was believed to be on his way to Sydney FC after reportedly signing a letter of intent to join John Kosmina's team.

But van Egmond said he hoped to retain the player, while Bridge himself said later he also wanted to stay.

"My understanding is that he's signed a letter of intent with Sydney, so it's one for his manager and obviously (our) management team to work out," van Egmond said.

"If it's up to me of course I'd love to keep Bridgey but of course we have to work within our salary restraints."

A delighted Bridge was reluctant to talk too much about his future, but asked if he wanted to remain at the club he said: "Yep, after that.

"I mean I wanted to stay before this, it's a great team and a great bunch of blokes."

Bridge is this week due to join the Olyroos side to face Mexico in San Francisco on Sunday and said he was unsure if he would hold contract talks with the club before that.

He was certain it wouldn't be tonight.

"No talking tonight, just drinking," Bridge said.

Bridge was quick to pounce on a defensive error by retiring Mariners veteran Tony Vidmar in the 64th minute.

He streaked away with the ball, dribbled past Central Coast defender Nigel Boogaard before unleashing a powerful shot past Mariners 'keeper Danny Vukovic just inside the penalty box.

"Scoring in any big game you always feel good scoring in a grand final the feeling is times ten," Bridge said.

Strike partner Joel Griffiths made his thoughts about Bridge's future with the club crystal clear when he jokingly crashed his teammate's conference with reporters after the match.

"He's staying here, what's going on?" Griffiths beamed cheekily.

"I'm his agent everything goes through me. He's staying definitely, we've got to talk about the clauses but once we got those put in I'm sure he'll be at Newcastle next year."
